I'd like to define an ldflags macro containing -rpath with $ORIGIN and

that will work for all build systems. Am I missing an option?
The “all build systems” requirement is pretty wide. Not every linker we
have supports -rpath. Could you narrow it down a bit?
Let's set aside other linkers for a moment...
If I want to run something like "mock ... --define '_pkg_extra_ldflags
-Wl,-rpath,$ORIGIN/../$LIB' --rebuild <src.rpm>" for an autotools
project, the value of that ldflags macro is going to end up in a
Makefile, where '$' will be interpreted as the beginning of a variable.
So, to use $ORIGIN in an autotools project, I need to escape the '$'
characters. But something like a python module with an extension doesn't
use make, so I have to escape that character in a different way.
It's possible that I'm missing a generic solution, but the one that
comes to mind is to write ldflags to a file and use -specs to pass the
arguments without the '$' being interpreted by the build system.
