In binutils 2.29, the behavior of the ADR instruction changed so that 1 is

See: https://sourceware.org/bugzilla/show_bug.cgi?id=21458
By using adr with a label that isn't annotated as a thumb function,
we avoid the new behaviour in binutils 2.29 and get the same behaviour
as in prior releases, and as in other assemblers (ms armasm.exe,
clang's built in assembler).

Looks less intrusive, I guess it should be ok even if feels a little
brittle somehow.
