toolchain: add powerpc SPE ABI support
Add the ability for buildroot to build an SPE ABI enabled toolchain.
This is mandatory for e500v1/v2 cores since they don't support classic
FPU mode as the e500mc does.
Useful for Freescale's PowerQUICC III and single/dual-core QorIQ
line of processors.
The new TARGET_ABI variable is used rather than TARGET_CFLAGS for
uclibc's UCLIBC_EXTRA_CFLAGS to avoid breakish CFLAGS leaking in, a
good example being -mthumb for ARM.
