#  A Generic sh config.arch that can be included by other platforms
#  to reduce the number of places that need to be edited when something
#  common changes.  If you include this file you may provide:
#
#  CPUFLAGS            - cpu specific flags to pass to the compiler
#  VENDOR_CFLAGS       - vendor specific flags to pass to the compiler
#  LOPT                - library optimisation flags
#  UOPT                - user optimisation flags
#  GLIBC_TARGET_OPTS   - flags needed for gcc
#  DISABLE_SHARED_SLL  - Force openssl to not be shared.
