gmp: Fix wrong detection of -march flag
Configure detects -march flag based upon target
triplet, it wrongly passes -march=armv4 for all
arm, this is unearthed when compiling with clang
since it errors out with flags like
/tmp/kraj01/a-0c2038.s:27: Error: selected processor does not support `bx r0' in ARM mode
since it does not pass --fix-v4bx along with
-march=armv4, which does not happen with gcc
toolchain since this flag is passed impicitly hence
this error was indetected
Fixed thusly
