This adds a test_ldflags function for testing linker flags without
adding them to LDFLAGS like check_ldflags does.

This adds the possibility to set foo_if and foo_if_any variables,
causing foo to be enabled if all/any of the listed options are
enabled.

Fixes issue1564

This in particular ensures that -DPIC is set appropriately for YASM, which avoids
linking failures on x86_64 for compilers that have PIE enabled by default
(e.g. hardened Gentoo).
It also makes the macho64 special-case hack adding -DPIC to YASMFLAGS obsolete.

and -DPIC makes little sense without -fPIC or similar - if -fPIC is
enabled by default, libavutil/internal.h defines PICi anyway.
Originally committed as revision 20486 to svn://svn.ffmpeg.org/ffmpeg/trunk
This covers the previous case of x86_64 and shared, but also
works with --enable-pic.
For 32 bit x86 it currently makes no difference since x86inc.asm
ignores -DPIC for non-x86_64.

At least for cross-compilation with Gentoo gcc 4.4.2 it fixes the build errors
due to GPREL 22 being insufficient for the .bss size of > 4 MB without it.
Why these errors do not appear with static builds is unclear, it is not due
to PIC (shared builds with PIC disabled show the same issue).

Add dependency generation commands compatible with Sun Studio.

Recent versions of gcc generate movw/movt pairs, and the linkers fail
to handle the associated relocations properly. Those responsible at
Codesourcery have refused to consider fixing this. Blame them for
making shared libraries slower than they need to be.

ebx_available if both "b" constraint and exb clobber code compile.
This is to fix compilation with Mac OSX 10.5.8's gcc 4.0.1 in 64
bit mode (-m64) which only fails for ebx/rbx clobbers but not
"b" constraints - this is probably a compiler bug.
Originally committed as revision 20107 to svn://svn.ffmpeg.org/ffmpeg/trunk
The test using clobber incorrectly indicates ebx to be available with the
default compilers on OpenBSD 4.5 and Haiku.

Apparently some versions of armcc do not identify as RVCT. This
changes the test to a string used by all versions.

Remove gcc-specific hacks and allow filling relevant information for non-gcc

As a sideeffect this moves more interesting variables to the top of config.mak.

if the "shared" var has not been explicitely enabled, rather than if
it has been explicitly disabled.
This way is not necessary to explicitly disable shared libraries in
order to have a pc file usable with only static libraries.

libx264 recently started mangling the name of x264_encoder_open() to
prevent version mismatches, breaking our test. Checking for another
function instead makes it work again.

This makes comma-separated patters to --disable-decoder and friends
work correctly with POSIX-compliant shells.

Using this flag enables position-independent code even when not strictly
required. It is impossible to use --disable-pic to forcibly disable PIC
when other properties mandate it.

Recognise AVR32 processor names as well as the generic "ap" and "uc"

We do the same for libschroedinger and already use pkg-config to generate
the CFLAGS for libdirac anyway, so there is no new dependency.
Thanks to Kovensky for reporting breakage on IRC.

When running behind ccache, the output from -MMD is corrupted unless
we also use the -MF and -MT flags.
Since ccache is difficult to detect and gcc 2.x doesn't support the
-MF and -MT flags, we always use the old dependency generation method
when gcc 2.x is detected.

-mdynamic-no-pic is required for it, but it was only
added to CFLAGS and the check only used ASFLAGS.

The argument to these options is now a comma-separated list of shell
patterns, e.g. --disable-decoder='indeo*,rv*'
Originally committed as revision 19604 to svn://svn.ffmpeg.org/ffmpeg/trunk
The name can now be a standard shell pattern. For example,
--disable-encoder=* disables all encoders.

This requires a gcc version with -march=native or -mcpu=native support,
which is somewhat random for non-x86.
