libgit2 1.8: TreeToTreeDiffTest#test_each_line_patch_header fails

Hi! 👋

We're currently rebuilding everything against libgit2 1.8 on Arch Linux.
With current ruby-rugged 1.7.2 I noticed one test failure when rebuilding:

This is a bug in libgit2 AFAICT, see libgit2/libgit2#5893 (comment)

Hello,

Doing build at FreeBSD with libgit2 1.8.1 and buid fails with:

<snip>
Building native extensions with: '--use-system-libraries'
This could take a while...
ERROR:  Error installing rugged-1.7.2.gem:

libgit2 version is not compatible, expected ~> 1.7.0
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Am I missing something here or libgit2 1.8.1 isn't supported yet?

Full log here

Thanks

Thanks
