Must be the influence of mutant aliens.

I see that the compiler is being executed like

/usr/bin/cc -I/usr/local/include -I/home/bfriesen/src/gnu/libtool-head/libltdl

and I believe that the -I/usr/local/include is being picked up from 
/usr/local/share/config.site.

This sort of problem may be avoided by setting CONFIG_SITE to point at 
some empty file while the tests are run.  This seems to be common for 
tests and I believe that it is already done for the 'old' tests.  Long 
ago, CONFIG_SITE was set to /dev/null but this caused issues for a few 
targets.

The most recent change related to the setting of CONFIG_SITE is 
mentioned in ChangeLog.2003:

2003-03-28  Richard Dawe  <address@hidden>

        * tests/defs: Set CONFIG_SITE to /nonexistent, except on DJGPP,

It seems that some/all of the new tests are not picking up this 
environment.
