gdb/testsuite: tests for debug lookup within the sysroot
Add tests for looking up debug information within the sysroot via both
build-id and gnu_debuglink.
I wanted to ensure that the gnu_debuglink test couldn't make use of
build-ids, so I added the 'no-build-id' flag to gdb_compile.
As these tests rely on setting the sysroot, if I'm running a
dynamically linked executable, GDB will try to find all shared
libraries within the sysroot. This would mean I'd have to figure out
and copy all shared libraries the executable uses, certainly possible,
but a bit of a pain.
So instead, I've just compiled the test executable as a static binary.
Now there are no shared library dependencies.
I can now split the debug information out from the test binary, and
place it within the sysroot. When GDB is started and the executable
loaded, we can check that GDB is finding the debug information within
the sysroot.
