Subject: Merge branch 'en/make-libgit-a'
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=282a9684ab6f176e830665ca1071a85d59bb6665;p=thirdparty%2Fgit.git

Merge branch 'en/make-libgit-a'

Instead of three library archives (one for git, one for reftable,
and one for xdiff), roll everything into a single libgit.a archive.
This would help later effort to FFI into Rust.

* en/make-libgit-a:
  make: delete REFTABLE_LIB, add reftable to LIB_OBJS
  make: delete XDIFF_LIB, add xdiff to LIB_OBJS
