<pre>The Linker/subprogram-linkonce-weak.ll test FAILs on Sparc, both
sparcv9-sun-solaris2.11
and sparc64-unknown-linux-gnu. So this seems like a generic Sparc issue rather
than being related to Solaris.

* On amd64-pc-solaris2.11, the DW_TAG_compile_unit entry for bar.c is followed
by
0x0000002a: DW_TAG_subprogram
DW_AT_name ("foo")
DW_AT_decl_file ("/path/to/dir/bar.c")
DW_AT_decl_line (1)
DW_AT_external (true)
DW_AT_inline (DW_INL_inlined)
and only then by the DW_TAG_subprogram entry for bar.
* On sparcv9-sun-solaris2.11 however, after the DW_TAG_compile_unit entry for
bar.c follows imediately the DW_TAG_subprogram entry for bar.
