[patch/rfc] handle GNU stack markings

[Mike Frysinger]

the asm match code does not include GNU stack markings which can cause gzip to 
require an executable stack on some linux architectures

i know the attached patch [which comes from Fedora] is not the right solution, 
but i'm not entirely sure which direction you guys want to go ... some 
projects add configure tests to see if the toolchain cares about the GNU 
stack while some people see if the toolchain supports -Wa,--noexecstack while 
others would just wrap it in like '#if defined(__ELF__) && 
defined(__linux__)'

Ripped from Fedora.
Include stack markings in the asm code so the final binary 
isn't assumed to require executable markings.
