Ouch. When porting, does this mean you need to look for places where GNU 
source code says "x86_64" and replace many of these places with "amd64" 
before building? That sounds error-prone.

Thanks for reporting that. That's due to a quoting typo in Gnulib's 
m4/stack-direction.m4. I fixed it by installing the attached patch into 
Gnulib. Grep will get this fix the next time it merges from Gnulib. In 
the meantime you should be able work around the problem by changing that 
'char *argv' to 'char *argv[]' in 'configure'.

This is after you modified 'configure', right? Otherwise "result: 
unknown" should result in STACK_DIRECTION being 0, which 
gnulib/lib/stackvma.h does not support (perhaps it should?).
