  Starting with ld.lld-17, ld.lld is invoked with the option
--no-undefined-version enabled by default. This causes ld.lld to error whenever
a versioned symbol map contains undefined symbols. As a result, ld.lld emits
errors when building libctf.

Together these patches fix the undefined symbol errors that occur when building
libctf.

Special thanks to Sam Jones and Nick Alcock for their assitance in creating this
patch set.

Fixes Gentoo bug 914640 (https://bugs.gentoo.org/914640)
