Reimar Döffinger [Sun, 10 Nov 2013 08:02:51 +0000 (09:02 +0100)]
Add --enable-rpath option to add -Wl,-rpath to pkg-config files.

This allows installing into e.g. /usr/lib/ffmpeg and binaries linked
against ffmpeg will pick these .so file while binaries linked against
some fork or different version will pick the libraries in /usr/lib.
There will be still some issues for binaries that (indirectly) end up
depending on multiple variants, but for the simpler cases it should allow
different applications to use different (compatible) variants that
are installed at the same time.

configure: Avoid requiring c99wrap for working around msys path issues

Msys is unable to convert unix style absolute paths to windows style
paths when combined with certain multichar MSVC options such as
-Fo<file>. We used to work around this issue by passing them as two
separate parameters separated by a space to c99wrap, which then mapped
them back to the actual parameter format that MSVC uses.

The only paths that actually are an issue are absolute unix style
paths, and the only place such absolute paths are used with the output
arguments (-Fo, -Fe, -Fi, -out:) are for the temp files within configure.

By setting TMPDIR to . for msvc/icl builds, we never need to use
absolute unix style paths for the file output, and we can use the
actual proper form of the file output parameters. This avoids requiring
the c99wrap wrapper for remapping the parameters for cases where the
c99 converter isn't invoked at all (MSVC2013 and ICL).
