H.J. Lu 5148d2e38f Add BUILD_NO_PIE_CFLAGS and BUILD_NO_PIE_FLAG 
We shouldn't use NO_PIE_CFLAGS and NO_PIE_FLAG with CXX_FOR_BUILD
when CXX_FOR_BUILD != CXX.  This patch adds BUILD_NO_PIE_CFLAGS
and BUILD_NO_PIE_FLAG to use with CXX_FOR_BUILD.  They are set to
NO_PIE_CFLAGS and NO_PIE_FLAG when build machine == host machine.
Otherwise, they are set to NO_PIE_CFLAGS_FOR_BUILD and
NO_PIE_FLAG_FOR_BUILD.
