configure's `mandir` has unusual behaviour

[thesamesam]

Nick and I already discussed this a bit but filing a bug so I don't have to juggle so much in my head.

With the usual mandir (the base of the man directory, not a specific category), we end up with dtrace.8 being installed into mandir, not the correct category subdir.

I had to adjust the ebuild like:

-               --mandir="${EPREFIX}"/usr/share/man
+               --mandir="${EPREFIX}"/usr/share/man/man8

See https://bugs.gentoo.org/938209 and 850a084b7f9ba426afb1febec97c613c90498484 in gentoo.git.

This is already fixed in the relocatable dtrace patch series

Can someone add a ref to the commit that fixes it. As far as I know that should already be on devel.

I must have hallucinated fixing it. Fix on the internal gentoo bugfixing branch now.

Thanks!

Unfortunately, the fix isn't quite right for DESTDIR:

	install -m 644 $(dtrace_DIR)/dtrace.8 $(INSTMANDIR)/man8

We end up with:

 * CMP: =dev-debug/dtrace-9999 with dev-debug/dtrace-9999/image
 *  FILES:-usr/share/man/man8/dtrace.8.xz
 *  FILES:+usr/share/man/man8.xz
 * ------> FILES(+1,-1)

Ugh. I tested this, dammit. Fixing.
