mk: adjust options for mingw cross compilation 



Check compiler target triplet for the strings 'windows' or 'mingw'
and set OS to Windows. If found, adjust basic parameters:

Set EXEEXT to indicate executables have .exe suffix.
Exclude 'relro' and 'now' flags which are not recognised on Windows.
Exclude 'noexecstack' flag which is not recognised on Windows.
Exclude -pthread flag because Windows doesn't have POSIX threads.
Include libssp.a to support stack-protector and _FORTIFY_SOURCE.
