The provided -march flags, especially for ARMv5 and ARMv6 may not necessarily match the needed ones: for ARMv5, it might be armv5, armv5te, armv5t, etc. If the wrong one is used, the incorrect toolchain sysroot can be used in a multilib toolchain. Therefore, let the user building OpenBLAS pass the appropriate -march flag. The other flags, such as -mfpu=vfp or -mfloat-abi=hard are kept, as they are actually required for the build to proceed (OpenBLAS uses VFP instructions, and assume an EABIhf ABI).
