configure: use -O3 with mingw 7.2.0
...
Older versions suffered from issues such as segmentation faults on
startup with optimization levels higher than `-O2` or with
`-fipa-icf`. v7.2.0 is OK, though.

configure: get real version for clang(++)
...
`clang++ -dumpversion` always outputs 4.2.1 as it was designed to be
compatible with `g++` in that version. So parse `clang++ --version`
for `clang++` instead.

build system: only use -O2 with 32bit mingw cross compilers >= 5.1.0

MXE has recently reverted to 4.9.x, and that line still produces fine
binaries with -O3.

Recent versions of the MXE mingw cross compilers produce stack-smashing
binaries with -O3 for some of the tools.
