Title:
EpicsHostArch script does not detect recent MSYS2/MinGW setups on
Windows

Bug description:
On MSYS2/MinGW installations, the EpicsHostArch script does not
recognize the host platform correctly.
64bit:
$ ./startup/EpicsHostArch
lib/perl/EpicsHostArch.pl: Architecture 'x86_64-msys-thread-multi' not recognized
32bit:
$ ./startup/EpicsHostArch
lib/perl/EpicsHostArch.pl: Architecture 'x86_64-msys-thread-multi' not recognized
Which is not surprising, as the underlying MSYS2 subsystem is the
same, and the difference is in the environment settings that point to
the appropriate toolchain.
64bit:
$ echo $PATH
/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl
$ printenv | grep MSYSTEM
MSYSTEM_CARCH=x86_64
MSYSTEM_CHOST=x86_64-w64-mingw32
MSYSTEM_PREFIX=/mingw64
MSYSTEM=MINGW64
32bit:
$ echo $PATH
/mingw32/bin:/usr/local/bin:/usr/bin:/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl
$ printenv | grep MSYSTEM
MSYSTEM_CARCH=i686
MSYSTEM_CHOST=i686-w64-mingw32
MSYSTEM_PREFIX=/mingw32
MSYSTEM=MINGW32
NB: I am impressed by the clarity and simplicity of MSYS2 / MinGW
