When running test-case gdb.base/psym-external-decl.exp with gcc-10, we have:
...
(gdb) print aaa^M
'aaa' has unknown type; cast it to its declared type^M
(gdb) FAIL: gdb.base/psym-external-decl.exp: print aaa
...
With an an earlier version, gcc still emits the debug info for the
declaration of aaa:
...
<0><d2>: Abbrev Number: 1 (DW_TAG_compile_unit)
<d8> DW_AT_name : psym-external-decl.c
<1><f4>: Abbrev Number: 2 (DW_TAG_variable)
<f5> DW_AT_name : aaa
<ff> DW_AT_external : 1
<ff> DW_AT_declaration : 1
...
but with gcc-10 that's no longer the case.
Fix the test-case by adding a use of aaa in psym-external-decl.c.
That still doesn't work for clang, so skip test in that case.
Tested with x86_64-linux, with gcc 7.5.0, gcc 10.0.0 and clang 5.0.2.
Also tested by reverting corresponding fix and ensuring test-case still
fails.
