libc/uClibc: fix verbosity level for uClibc >= 0.9.30

uClibc >= 0.9.30 supports three verbosity levels, according to "make help":

V="" - Quiet build (default)
V=1 - Brief build (show defines, ld flags)
V=2 - Very verbose build

I think older versions of uClibc treat V=2 the same as V=1.
For current uClibc, only V=2 shows the full command lines.

scripts/functions: recognise Cygwin build hosts

scripts: use 'hg archive' to create release tarballs

kernel/mingw32: mark as being EXPERIMENTAL

configure: fix --mandir

--mandir points to the base dir of the man pages, so
we have to append our man section below given dir.

scripts: update config.{guess,sub}

Merge.

complibs/ppl: backout #9f0de857cb05

The patch breaks the build on most machines,
while the purpose of the patch is dubious.
So, simply back it out.

debug/gdb: properly remove build tic

tic is isntalled in buildtools, not in the toolchain's bin dir.
Plus, it may have an extension...

debug/gdb: Fix compilation for Mingw hosts

GDB requires PDcurses instead of ncurses while running on Windows.
So, do not always compile ncurses in case GDB needs to build.

PDcurses is provided by an earlier build step and is not described in
this file.
