commit 075fa4cd9ae2ee5e9715fad2f70b2092ddc9ac2d

    Mostly revert "build: add support for fixing up library soname"
    
    This reverts commit b12288fa69b171f7c9405518c9bed3581a06f7ce.
    The patchelf approach is too fragile, and the only users of this have been
    converted to make patching unnecessary
    Leave the abi_version_str variable in place in rules.mk
