Otherwise gdb will print a spurious warning each time gdb is used:
warning: .dynamic section for "/system/bin/linker" is not at the expected
address (wrong library or version mismatch?)
BUG:6946614
Change-Id: Ib21b8db0615751189c1601140deb43bc089289b6
Add a GNU_STACK marker to crtend* files. This tells the linker
that these files do not require an executable stack.
When linking, a missing GNU_STACK marker in any .o file can prevent
the compiler from automatically marking the final executable as NX
safe (executable stack not required). In Android, we normally work
around this by adding -Wa,--noexecstack / -Wl,-z,noexecstack.
For files like crtend.S / crtend_so.S, which are included in every
executable / shared library, it's better to add the GNU_STACK note
directly to the assembly file. This allows the compiler to
automatically mark the final executable as NX safe without any
special command line options.

This reverts commit 8793e7c7d2,
and fixes the build by building upstream NetBSD source as a
separate library that's then swallowed whole into libc_common.

There were two bugs in our implementation. Intel found one, but another
remainined, and tracking upstream is the way forward for functions where
we add no value.

Remove the hand-collated ones, and switch to a script that pulls the
copyright headers out of every file and collects the unique ones.

These are dead. I cleaned up external/ a long time ago, but didn't
realize there were any in the main tree.

Also make the errors more readable, since none of us seemed to know
what they actually meant. The new style is still as verbose as the
old, but that's probably necessary in the absence of chained exceptions
in C. Here's what you'd see if you try to boot after removing
libsurfaceflinger.so:
32267 32267 E AndroidRuntime: java.lang.UnsatisfiedLinkError: Cannot load library: (linker.c:1629, pid 32259) soinfo_link_image: could not load library "libsystem_server.so" needed by "libandroid_servers.so"; caused by (linker.c:1629, pid 32259) soinfo_link_image: could not load library "libsurfaceflinger.so" needed by "libsystem_server.so"; caused by (linker.c:709, pid 32259) load_library: library "libsurfaceflinger.so" not found
This patch also fixes almost all of the compiler warnings.
