This is a fix over commit a150b26ee8
On a MINIX station, the tools are not usually built and
on a first-time building of the tree, the fetching script
of texinfo was not triggered in some cases. Let force it.

As of change git-87c599d, when processing CLOCK notifications, PM no
longer set the current process pointer 'mp'. That pointer is however
used when delivering signals through check_sig(), to see whether the
current process may deliver a signal to the target process. As a
result, delivering SIGALARM signals used a previous pointer in these
checks, causing alarm signals not to be delivered in some cases.
This patch ensures that alarm signals are again delivered with PM as
current process.

- clear "revents" fields even when the call times out;
- do not call FD_ISSET with a negative file descriptor number.

With this patch, it is now possible to generate coverage information
for MINIX3 system services with LLVM. In particular, the system can
be built with MKCOVERAGE=yes, either with a native "make build" or
with crosscompilation. Either way, MKCOVERAGE=yes will build the
MINIX3 system services with coverage profiling support, generating a
.gcno file for each source module. After a reboot it is possible to
obtain runtime coverage data (.gcda files) for individual system
services using gcov-pull(8). The combination of the .gcno and .gcda
files can then be inspected with llvm-cov(1).
For reasons documented in minix.gcov.mk, only system service program
modules are supported for now; system service libraries (libsys etc.)
are not included. Userland programs are not affected by MKCOVERAGE.
The heart of this patch is the libsys code that writes data generated
by the LLVM coverage hooks into a serialized format using the routines
we already had for GCC GCOV. Unfortunately, the new llvm_gcov.c code
is LLVM ABI dependent, and may therefore have to be updated later when
we upgrade LLVM. The current implementation should support all LLVM
versions 3.x with x >= 4.
The rest of this patch is mostly a light cleanup of our existing GCOV
infrastructure, with as most visible change that gcov-pull(8) now
takes a service label string rather than a PID number.

Some files in LLVM have more than Minix-maximum of 60 characters.
Also drop some obsolete stuff, and add obj which are symlinks added
to every directory when using /usr/obj as OBJDIR (hinted in wiki.)

The way these options work is by creating files that contain debugging
symbols and stashing them in a dedicated set. The minix-debug set has
been created for this purpose, but it will probably have to be refined
since it has been tested only with the default options with an i386
cross-build.
LSC: Amended to support many combination of MKDEBUG, MKDEBUGLIB, with
and without X11, for both intel and arm.

Split the process to fetch GNU tools (until now embedded
within tools/Makefile.gnuhost) into a new Makefile.fetchgnu,
MINIX-specific hence relocated, which is to be also used
to fetch sources even when not building the tools.
Use it for binutils too.
Improve documentation.
Also do not run configure on each run when MKUPDATE=yes
The .WAIT serialization instruction between fetching and other
configure sources was raising a new run of configure at each
compilation. Avoid it by using two rules.
