Jürgen Buchmüller 7cec629479 icecat: update to 68.6.1
One has to roll hew own tarball with the IceCat 68 branch.
There are no official release tarballs anymore as it seems.
https://git.savannah.gnu.org/cgit/gnuzilla.git/log/?h=68

The result of me running ./makeicecat is available on my
https://distfiles.voidlinux.de site. It should perhaps be moved
to voidlinux.org distfiles.

Problem description: Tab-titles that are too long to fit into a tab get faded out.
On big endian this is broken and instead of fading out, the
tab gets white and the font transparent, leading to an unreadable
tab-title
Solution: This is not a real solution, but a hack. The real solution would have been
to byte-swap the correct buffer, but I could not find it.
So the next best thing is to deactivate the fading-effect. Now all tab-titles
are readable, albeit not as pretty to look at as they could be.
Side-effects: I have not yet found an unwanted side-effect.
