Stripping does not work for .a files
In abuild, automatic debug information separation as done by
default_dbg() does not separate debug info from static .a libraries,
causing them to bloat in size immensely.
For instance, with the LLVM package, simply adding a $pkgname-dbg
subpackage causes the llvm4-static package to bloat in size to 1.7GB.
It seems like stripping is also not applied to .a files in general, leading to probably needless code bloat.
