# Modified by Stuart Winter <mozes@slackware.com> for Slackware ARM.

# Notes:
# [1] Some parts of the gcc suite do not work for ARM so they are currently
#     missing; this isn't an oversight on my part - they simply don't work! ;-)

# Record toolchain & other info for the build log:
slackbuildinfo

# Paths to skeleton port's source & real Slackware source tree:
slackset_var_cwds

# Determine the CFLAGS for the known architectures.  If you specify -mtune=xscale
# for ARM then the build breaks.
# Also disable libspp (Stack Protector) because with gcc 4.2.3, code compiled
# with it tends to segfault.  Unfortunately, many newer releases of sources
# check for -fstack-protector & use it if available; glibc is one of these.
