Test suite failures

[pipcet]

make check output is currently:

# of expected passes		41
# of unexpected failures	4
# of unsupported tests		3

with the following failures:

FAIL: nm --size-sort
FAIL: strip with saving a symbol
FAIL: simple objcopy of executable
FAIL: strip executable with saving a symbol

These need fixing.

Now I've made dejagnu recognize our targets as ELF, the output is:

# of expected passes		135
# of unexpected failures	10
# of unsupported tests		7

with these failures:

FAIL: strip with saving a symbol
FAIL: simple objcopy of executable
FAIL: strip executable with saving a symbol
FAIL: merge notes section (32-bits)
FAIL: unordered .debug_info references to .debug_ranges
FAIL: objdump -WL
FAIL: readelf -r
FAIL: readelf -wi: missing: .*DW_TAG_compile_unit.*
FAIL: readelf --debug-dump=loc
FAIL: readelf -wiaoRlL

Okay, I finally discovered there are separate test suites for binutils, gas, and ld.

The gas testsuite passes now, except for some expected and harmless failures.

The binutils testsuite has a single failure, the "simple objcopy" test at #4.

The ld testsuite has numerous failures, many related to two things:

• we don't have a .text section. We can't have a .text section either, since that's expected to be both the section where code goes and the section offsets into which describe function entry points. Those are separate sections for us.
• dynamic libraries need to be turned into WebAssembly modules before the test case can find them.

The current stats are:

		=== ld Summary ===

# of expected passes		506
# of unexpected failures	110
# of expected failures		4
# of unresolved testcases	3
# of unsupported tests		108

Okay, passing all tests now, though this required some massaging of test conditions and some hacks for dynrelro support...which doesn't even make sense as long as there is no read-only memory in wasm.
