With -g, and a code section that ends unaligned, the assembler complains of
"unaligned opcodes detected".  Except there are no such unaligned opcodes, nor
dwarf2 code ranges covering the end of the section, which arguably makes this
an assembler bug.  However, it's reasonably easy to work around in the
compiler, which saves having to bump the required binutils version.

Tested on aarch64-linux.


Ok for the varasm bits.
