jom is a general make replacement now

[Patrick Spendrin]

Hi everybody,

with version 1.01 the make replacement jom now also works with the
makefiles cmake generates for mingw.

Please test this version (available by running emerge --target=101 jom)
and tell me if it works under your compilers (msvc2010, msvc2008,
mingw4, mingw-w64, mingw-w32 and the CE stack)

If no problems occur, we will make jom the default make for all
compilers soon.

regards,
Patrick
