We set GCC_EXEC_PREFIX when testing in-tree GCC because we want the GCC we're
testing to search the right paths.
Note that in creating site.exp, we do:
@echo "set GCC_EXEC_PREFIX \"$(libdir)/gcc/\"" >> ./tmp0
If I understand correctly, the issue in:
http://gcc.gnu.org/ml/gcc-patches/2006-12/msg01493.html
may be that DejaGNU wants to compile testglue, and therefore needs
GCC_EXEC_PREFIX set at that point, since testglue is of course built with the
compiler being tested.
Maybe HOSTCC should be "GCC_EXEC_PREFIX= gcc"?
