Commit 8bec63bf92d8dd028aa88dbd5109c314cdb9ebea attempted to switch to
using -fdebug-prefix-map to set file locations in debug packages. It
make a few mistakes...
1) Adding debug C{,XX}FLAGS only worked if DBGSRCDIR was defined in
makepkg.conf. Fix this by falling back to the default value.
2) Using -fdebug-prefix-map altered a lot of assumptions about file
locations when copying source files into debug packages. This resulted
in lots of messages of failed cp in packaging output.

In commit 8b0d59b83a60eb504567590346119fe4cd891cad support was added for
storing the source files of binaries in debug packages. This made use of
the debugedit program which is part of the RPM package manager, which is
not very standalone.
The same effect can be achieved using -fdebug-prefix-map, an option
accepted by both the gcc and clang compilers which modifies how the
compiler itself stores the references to the source files rather than
requiring us to later edit the produced binaries. This also removes the
dependency on external programs like debugedit.
As a result of this change, source files will only be effectively added
for programs which actually use the exported CFLAGS. This is a reasonable
tradeoff as we expect our CFLAGS to be used rather than ignored. Upstream
software which do not produce useful debug packages are expected to fix
their build systems to respect the environment CFLAGS.
As a result of this change, the routine for extracting source filenames
from binaries had to be modified to derive the source file from the
final debug location, rather than the other way around.

storing the source files of binaries in debug packages. Allow the user
to specify where those source files should be stored via makepkg.conf

Debug packages are fairly useless currently because the soucre files needed
for stepping through code etc are not packaged with them. This patch adds the
needed source files to the debug package and adjusts the debug info to look at
the /usr/src/debug/ directory for them rather than the build location. This
requires using the "debugedit" program which is provided as part of the RPM
sources.

We want to provide source files with debug symbol packages to allow easy
stepping through the program. This becomes difficult with split packages due
to the binaries in many of these sharing source files across packages.
There are (at least) two solutions to this problem. #1: ensure common source
files are located in the debug package for the package lowest in the dependency
chain and add dependencies to the debug packages so all require source files
are present, or #2: create one debug package for all split packages in a
PKGBUILD. The second is a more robust approach despite potentially creating
very large debug packages.
This patch creates a single $pkgbase-debug package and adds provides such that
installing $pkgname-debug will always work.

To add a new packaging option, drop a file into libmakepkg/tidy that contains
a 'packaging_options+=('<option>') and a function that implements that
option. The function needs added to the 'tidy_remove' array if it removes
files or the 'tidy_modify' array otherwise.
