package/pkg-generic: tweak only .la files that need it
Currently, when we tweak the .la files, we do so unconditionally on all .la files, even those we already fixed in a previous run. This has the nasty side effect that each .la file will be reported as being touched by all packages that are installed after the package that actually installed said .la file. Since we can't easily know what files were installed by a package (that is an instrumentation hook, and comes after the mangling), we use a trick (like is done in libtool?): we do mangle all files, each into a temporary location; if the result is identical to the input, we remove the temporary, while if the result differs from the output, we move the temporary to replace the input.
