5135b3ae6e linker: don't perform unnecessary mprotects 
The linker only needs to mark the text segment as
writable iff the file has text relocations. Unnecessarily
calling mprotect when it isn't necessary is slow, and some
security enhanced kernels don't like it. Pages which are
simultaneously writable and executable are considered a no-no.

The vast majority of executables / shared libraries on Android
do NOT have text relocations.

6eee1fc68f crtend*: Add GNU_STACK note 
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.
