Thanks to testing by sabotage users (failed Perl build), I've
identified and fixed a regression in shared library support on ARM.
The ctor/dtor support code's references to init_array and fini_array
were not properly marked hidden and thus were not being resolved at
link-time, leaving (ignored) textrels in the library.
Anyone using musl 0.9.9 on ARM should apply this patch before
attempting to build shared libraries:
http://git.musl-libc.org/cgit/musl/commit/?id=d432b2c057fc64256645422382c2f7e32c45b3cc
The broken code is part of crt[in].o, not part of libc.so, so if you
do experience breakage from this issue, the remedy is to relink your
shared library files that were linked using the bad crt[in].o files,
not to replace musl's libc.so. Since musl itself does not link with
any startfiles, libc.so is unaffected by the issue.
