A little hack to keep C++ crap out of libsdl.

Problem is that autotools isn't smart enough to realize that libarch.la
should be linked as C++ only for TARGET_BEOS ... otherwise it should be
linked as a good old fashioned C library.

Since Gentoo doesn't support BEOS [atm], this hack is acceptable considering
the gain (no more C++ crap !).
