Tesseract for FreeBSD was built without support for SSE4.1, AVX,
AVX2 or FMA because it uses a different value for `host_cpu`.

The old code failed with an error message when running in a
git working directory without any tag (for example after
git clone --depth 1).

MSYS2 clang64 uses the lld linker which does not support --as-needed.
The normal GNU ld uses that linker option with ELF targets but ignores
it for PE targets (.exe, .dll), so it can be removed.
Remove also the -Wl, which is only needed when linker options are
passed to the compiler but not when they are directly passed to the
linker.

If no PKG_CONFIG_PATH was provided by the user, it is now set
automatically on hosts which have the `brew` command.
MacOS with Homebrew needs PKG_CONFIG_PATH to find icu4c and libarchive.

Using those flags is not acceptable for Linux distributions
because the resulting code then depends on the build
infrastructure, so the build result is not deterministic.
It is still possible to use those compiler flags by specifying
CXXFLAGS.

It is still possible to build Tesseract with double LSTM:
# autoconf
./configure --disable-float32
# cmake
cmake .. -DFAST_FLOAT=ON

The old commit only silenced parts of the build,
while the new one silences the whole build.

On latest MacOS 11.3 the system header file "ostream" includes a file
named "version".
The macro DEFAULT_INCLUDES adds the source root to the list of include
directories by default. As MacOS uses a case insensitive file system,
the compiler finds and includes the file "VERSION" there which causes
compiler errors and a failing build process.
Setting an empty DEFAULT_INCLUDES fixes that, but requires moving
config_auto.h to another directory in the include search path.

Don't abort if a brew catalog file is missing.
This is needed for the GitHub actions environment
which provides brew also for Linux.
Running cross builds then failed at AC_CHECK_FILE.
