tools/mpy_ld.py: Give better error for unsupported ARM absolute relocs.
This is a known limitation, so better to give a clear warning than a
catch-all AssertionError. Happens for example when trying to use
soft-float on ARCH=armv6m
Also give more details on the assertion for unknown relocations, such that
one can see which symbol it affects etc, to aid in debugging.
References issue #14430.
