With -fstack-protector, x86 -m32 needs __stack_chk_fail_local
defined in crtbegin_*.o.
Include __stack_chk_fail_local.S in begin.S otherwise linker
(which is built w/o crt*) may not link.

This patch adds a trivial implementation of snprintf() that calls
our internal vsnprintf().
Inspection of the generated machine code showed that the linker
contained a full implementation of stdio's vfprintf. It was pulled
in because the pthread implementation uses snprintf() somewhere.
ProTip: It's possible to see why specific objects files are included
in a final binary by adding the following to your Android.mk, then
looking at the content of /tmp/MAP.TXT:
LOCAL_LDFLAGS += -Wl,-Map=/tmp/MAP.TXT

Add strlcpy / strlcat support to FORTIFY_SOURCE. This allows
us to do consistency checks on to ensure we don't overflow buffers
when the compiler is able to tell us the size of the buffer we're
dealing with.
Unlike previous changes, this change DOES NOT use the compiler's
builtin support. Instead, we do everything the compiler would
normally do.

According to
http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html
realloc should NOT be marked with __attribute__((malloc)). Quoting:
realloc-like functions do not have this property as the memory
pointed to does not have undefined content.
For reference, __mallocfunc is defined in sys/cdefs.h as:
#define __mallocfunc __attribute__((malloc))

This patch adds to make the linker a little bit easier to understand
by making all functions that acts on a sofino object with a soinfo_
prefix.
This is to more easily distinguish functions that operate on global
state, and those that operate on individual libraries.
This should be purely stylistic, i.e. no feature/behaviour change.

sprintf FORTIFY_SOURCE protections are not available
on clang.
Also add various __attribute__s to stdio functions.

Add _FORTIFY_SOURCE support for snprintf, vsnprintf
At this time, we opt out of these protections for clang, as clang
does not implement __builtin_va_arg_pack().

Fix runtime error when snprintf() FORTIFY_SOURCE protections are
applied. The size passed to snprintf() is larger than the tmp
buffer size, which results in a runtime assertion failure.
Even though the size passed to snprintf is larger than the buffer,
there's no danger of overwriting the buffer because of the format
string passed to snprintf.

This was misleading 'configure' into thinking we actually support AF_LINK,
but we're Linux, so we don't, and we never implemented the functions we
declared here either.
