I find on i686-apple-darwin10 that the problem can be recreated with...
make -k check-libiberty
executed in the toplevel of the build directory. Interestingly, if I comment
out...
# Flags to pass to a recursive make.
FLAGS_TO_PASS = \
"AR=$(AR)" \
"AR_FLAGS=$(AR_FLAGS)" \
# "CC=$(CC)" \
"CFLAGS=$(CFLAGS)" \
in the generated Makefile in darwin_objdir/libiberty, the correct, xgcc,
compiler is used for those tests. Somehow the recursive make is broken
for libiberty and is silently using the system compiler.
