ftmemsim-valgrind/configure.ac
Petar Jovanovic fde6d8320b mips64: modify configure.ac to check for cavium supported toolchain 
Modify configure to check if we can pass -march=octeon or -march=octeon2
flags to the compiler. This part is required as it gives us information how
to compile (i.e. whether to compile) tests specific for Cavium Octeon boards.

Patch by Zahid Anwar, with minor modifications.

Related to Bugzilla issue 326444.

# Platform variants?
#----------------------------------------------------------------------------
# Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
# But there are times where we need a bit more control. The motivating
# and currently only case is Android: this is almost identical to
# {x86,arm,mips}-linux, but not quite. So this introduces the concept of
# platform variant tags, which get passed in the compile as
# -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
#
# In almost all cases, the <variant> bit is "vanilla". But for Android
# it is "android" instead.
#
# Consequently (eg), plain arm-linux would build with
#
# -DVGP_arm_linux -DVGPV_arm_linux_vanilla
#
# whilst an Android build would have
#
# -DVGP_arm_linux -DVGPV_arm_linux_android
#
# Same for x86. The setup of the platform variant is pushed relatively far
# down this file in order that we can inspect any of the variables set above.
