(cherry picked from commit 5f4bf24)

New android ndk (18) now uses clang. We were going through the wrapper
that are provided. This lead to surprising errors when building.
Ideally we could use the llvm linker as well, but this leads to errors
as many packages don’t support the llvm linker.

this isn’t useful any more because the ndk we use no longer supports it.

[19.03] virtualbox: 5.2.26 -> 5.2.28

LLVM should be target independent because it will work with all
machine types. This is different from GCC where it needs to know what
target to build ahead of time.

I switched to fetchFromGitLab for more transparency and because 2.10 is
not yet available on any Debian mirrors.
A drawback is that any dates in the man pages will now always be
set to 1970-01-01, because fetchFromGitLab removes the timestamps from
$src (not manually but by unpacking the archive).
