# 1. override CC to keep glibc's configure from using $TARGET-gcc.

# 3. build with gcc 3.2 or later
# Compare these options with the ones used when building glibc for real below - they're different.

# Alternately, we could put ${PREFIX}/${TARGET}/bin on the path.
# Set --build so maybe we don't have to specify "cross-compiling=yes" below (haven't tried yet)
# Note: the warning
# "*** WARNING: Are you sure you do not want to use the `linuxthreads'"
