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.

Changing from class to struct causes clang compiler warnings like this one:
In file included from ../../../src/api/baseapi.cpp:63:
../../../include/tesseract/osdetect.h:29:1: warning: class 'BLOB_CHOICE_LIST' was previously declared as a struct; this is valid, but may result in linker errors under the Microsoft C++ ABI [-Wmismatched-tags]
class BLOB_CHOICE_LIST;

BLOB_CHOICE_LIST

../../../include/tesseract/osdetect.h:29:1: note: did you mean struct here?
class BLOB_CHOICE_LIST;
^~~~~
As it is not possible to change the API header tesseract/osdetect.h,
some of the changes from class to struct had to be reverted.

CMakeLists.txt uses TREE (supported since cmake 3.8) and
check_ipo_supported (supported since cmake 3.9).
Require 3.10 which is provided by Ubuntu bionic and newer distributions.

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.
