PCH with gmake and -j2 or larger
Using premake 4.4 beta 5, creating a gmake project and compiling using make -jX with X>1, precompiled header support is not working quite right. The precompiled header is generated along with the source code, so the source files will abort with an error that they do not find the precompiled header.
Example for reproduction attached, run it with
premake gmake make -j4
(tested with premake 4.4 beta 5 binary for Linux)
