When in doubt - do the right thing.

Attached is a revised test.

This version allows for:

  * Assembling on the ARM which uses the @ character as a line-comment character.
  * Assembling on targets which do not support CFi directives.
  * Assembling on the SH which does not support unaligned .long directives.
  * Assembling on various targets which do not support relocations for .quad values.
  * Testing on targets which generate extra text in the readelf output - because readelf does not support the relocations used (yet)

The patch also skips the test for RISCV targets as they currently do not support
non-constant LEB128 expressions.

The only targets which still fail this test are HPPA and HPPA64, which I believe
is due to a real bug somewhere in their backend code.  I have not tracked down the
actual bug yet, but I felt that it was better to leave the test as failing (rather
than xfailing it) as a reminder that it needs to be investigated.

Cheers
  Nick
