I think that mtest should pass now on Darwin.  I think the dwarf5 tests may
still be failing.  This seems to be because dsymutil does not understand
dwarf5, at least on the compile farm macOS machine that I have access to.

current results [darwin16, darwin19] are:

PASS: allocfail.sh
PASS: test_elf_32
PASS: test_elf_64
PASS: test_macho
PASS: test_xcoff_32
PASS: test_xcoff_64
PASS: test_pecoff
PASS: test_unknown
PASS: unittest
PASS: unittest_alloc
FAIL: btest
FAIL: btest_alloc
PASS: stest
PASS: stest_alloc
PASS: edtest
PASS: edtest_alloc
PASS: ttest
PASS: ttest_alloc
FAIL: dwarf5
FAIL: dwarf5_alloc
FAIL: mtest

the reason for btest* and mtest fails is unknown at present.

Most likely the fails for dwarf5 would relate to whether dsymutil is yet
'dwarf5 aware' .. I believe the debug default for the system toolchain(s) is
dwarf4.

Using the most recent command line tools (XC12 beta5) on darwin19, dsymutil
actually aborts with the dwarf5 input.
