Jan-Marek Glogowski 22b6cfa35c firebird: build fixes (incl. parallel build)
The main idea is to get rid of the "unset MAKEFLAGS". AFAI can
see, the whole CPU stuff isn't used anymore. So we can drop the
whole FB_CPU_ARG handling. Since LO doesn't use any of make's
implicit rules, the build breaks, but luckily it just requires a
single rule for the btyacc build - just a Firebuild build tool.

Then there is the whole broken handling of LIBTOMMATH and
LIBATOMIC_OPS already in LO's configure.ac. I don't know if any
internal build of Firebird with these as system libs would work.
I guess people either have a system Firebird or also build with
internal libtommath and libatomic_ops. This fixes just the
obvious errors. I didn't try to build it, so there might still
be typos (TBH I thought hard about just dropping the system
build of these libraries, after seeing the broken configure.ac).

And I'm not sure our / the system boost preprocessor library is
ever used over the Firebird-internal copy. It also looks like
it's also just used in an other build tool and nothing of the
Firebird DB itself depends on it.

Then there is the movement of the install_name_tool / otool
patching on MacOS from the patch into the ExternalProject to
further shrink the patches, as the build doesn't depend on it.

This also introduces a different debug build mode for the
gcc-/g++-wrapper: MSVC_USE_INDIVIDUAL_PDBS.
It uses -Fd to write a separate PDB per output file instead of
using -FS to use sync writes to a single PDB, which might work
around the PDB access failures seen by Jenkins for linking
executables. In theory it's also faster and should work with all
the other wrapper users, but I don't want to open that can of
additional build errors (yet), for eventually marginal gains.
