[committed] Fix pr24170.sh on x32

[Tom de Vries <tdevries@suse.de>]

Hi,

For pr24170.sh on x32 we have:
...
dwz: 1: DWARF pointer size differs between CUs
dwz: 2: DWARF pointer size differs between CUs
dwz: Too few files for multifile optimization
FAIL: /<<PKGBUILDDIR>>/build/../src/testsuite/dwz.tests/pr24170.sh
...

The test-case uses the exec implptr-64bit-d2o4a8r8t0, which is build using:
- a .S file containing DWARF with pointer size 64.
- a main.c, which compiled for x32 will contain DWARF with pointer size 32
This explains the dwz failure.

Fix this by requiring a single pointer size in the exec.

Committed to trunk.

Thanks,
- Tom
