I left a comment on https://sourceware.org/bugzilla/show_bug.cgi?id=19109 that
the --enable-compressed-debug-sections=gas syntax needs extension to
support zstd.

Perhaps the easiest solution (and circumvents the syntax problem) is to
add a new option: --enable-zstd-compressed-debug-sections, but then
there is some duplication...
