yes that was the fix I had in mind.

sure, that would mimic the behaviour we did see before the glibc update, but
papering over the original issue.  In practice this shouldn't be an issue
because we only build static binaries in very few cases.

Bug description:
  Making a simple file conftest.c with the following contents:

  int main() { return 0; }

  And then compiling it on i386 with gcc -fPIE -pie -static conftest.c
  returns:

  *** Error in `/usr/bin/ld': corrupted double-linked list: 0x08dddb38
  ***

  This breaks compilation xorg-server on i386. I believe that -static
  -fPIE -pie is probably invalid, and it fails on amd64 too.

  $ gcc -fPIE -pie -static conftest.c 
  /usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/4.8/crtbeginT.o: relocation R_X86_64_32 against `__TMC_END__' can not be used when making a shared object; recompile with -fPIC
  /usr/lib/gcc/x86_64-linux-gnu/4.8/crtbeginT.o: error adding symbols: Bad value
  collect2: error: ld returned 1 exit status

  But autoconf hangs on the corrupted double-linked list, which times
  out the xorg-server build.
