[PATCH] [gdb/testsuite] Add boards/aslr.exp

[Tom de Vries]

Commit deb47060b58 ("gdb/testsuite: make gdb.dwarf2/dw2-empty-inline-ranges.exp
work when ASLR can't be disabled") notes that test-case
gdb.dwarf2/dw2-empty-inline-ranges.exp fails in case the test-case:
- produces a PIE executable, and
- is run in a setup that ignores disable-randomization == on (such as in a
  container where that capability is removed).

The commit fixes the test-case using nopie, but I wondered if there were more
test-cases that fail in the same way, so I ran the testsuite using:
- target board unix/-fPIE/-pie, and
- a patch that added -iex "set disable-randomization off" to INTERNAL_GDBFLAGS,
and indeed there are.

Add a boards file aslr.exp with this setup.

Tested on x86_64-linux.

Simon,

I just saw that you also submitted a version, so I'm dropping this one.

Thanks,
