ext-toolchain: Fix ARCH_SYSROOT detection
For the detection of the ARCH_SYSROOT_DIR (which contains the C library variant specific to the compiler flags), we used to pass only the -march argument instead of the full TARGET_CFLAGS. This was done because TARGET_CFLAGS contains --sysroot, and we don't want to tell here the compiler which sysroot to use, because we're specifically asking the compiler where the *normal* arch sysroot directory is. Unfortunately, there are some multilib variants that aren't decided only based on -march, but also on -msoft-float or other compiler flags. Therefore, we take the opposite approach: pass the full TARGET_CFLAGS, from which we have stripped the --sysroot option. For example, this allows a PowerPC CodeSourcery toolchain, on which we're using the soft-float multilib variant, to work properly as an external toolchain.
