x86_64/amd64 fails to build

[Joel Sherrill]

This is with waf and autoconf on master.

Short versions of failing configurations:

FAILED (2)  autoconf build of x86_64 amd64 (NOSMP/NOMP/DEBUG/PROFILE)
FAILED (1)  waf build of x86_64 amd64 (NOSMP/NOMP/DEBUG/PROFILE)
FAILED (2)  autoconf build of x86_64 amd64 (NOSMP/NOMP/DEBUG/NOPROFILE)
FAILED (1)  waf build of x86_64 amd64 (NOSMP/NOMP/DEBUG/NOPROFILE)

This is the error:
