[bug#73529] [PATCH core] gnu: patchelf: Build from git sources.

[attila . lendvai]

From: Attila Lendvai <attila@lendvai.name>

Rationale: it makes it much easier to build a pending PR by using
`(commit "pull/544/head")` in the origin, or in general to experiment
with different patchelf versions.  It also makes it more resilient
against attacks hidden in release tarballs.

sadly, this leads to endless rebuilds...
