Ross Burton 767e031645 Fix build race in Makefile
The current rule for the binaries is:

glew.bin: glew.lib bin bin/$(GLEWINFO.BIN) bin/$(VISUALINFO.BIN)

In parallel builds, all of those targets happen at the same time. This
means that 'bin' can happen *after* 'bin/$(GLEWINFO.BIN)', which is a
problem as the 'bin' target's responsibility is to create the directory
that the other target writes into.

Solve this by not having a separate 'create directory' target which is
fundamentally racy, and simply mkdir in each target which writes into it.
