configure: arm: detect toolchain default arch version
Probe for the toolchain default architecture version if no --cpu flag is present or an unknown cpu is specified. Works with gcc, clang and armcc. This allows configuring based on the arch version even if it is not explicitly specified to configure. It also causes an explicit -march flag to be added to CFLAGS and ASFLAGS, which in turn lets us do proper instruction set tests with the assembler. Signed-off-by: Mans Rullgard <mans@mansr.com>
