# 1. override CC to keep glibc's configure from using $TARGET-gcc.
# 2. disable linuxthreads, which needs a real cross-compiler to generate tcb-offsets.h properly
# 3. build with gcc 3.2 or later
# Compare these options with the ones used when building glibc for real below - they're different.
# As of glibc-2.3.2, to get this step to work for hppa-linux, you need --enable-hacker-mode
# so when configure checks to make sure gcc has access to the assembler you just built...
# 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'"
# *** add-on?"
# is ok here, since all we want are the basic headers at this point.
# Override libc_cv_ppc_machine so glibc-cvs doesn't complain
