description:
Fix GCC10 for arm.

Include order of bpapi.h and netbsd-elf.h was swapped when official
support for arm*--netbsdelf-eabi{,hf} was added to GCC10. This seems to
cause critical inconsistencies, which results in SIGSEGV for as(1) on
earmv6hf{,eb} and some other regressions for many arm variants.

With this fix, everything work just fine as far as I can see.

Thanks skrll and mrg for discussion!
