"make bootstrap" race condition

The following error occurs when building from the FreeBasic-1.06.0-source-bootstrap.tar.xz source code:

LINK bootstrap/fbc
AR lib/freebasic/linux-x86_64/libfb.a
gcc: error: lib/freebasic/linux-x86_64/libfb.a: No such file or directory
AR lib/freebasic/linux-x86_64/libfbpic.a
make: *** [makefile:1093: bootstrap/fbc] Error 1
make: *** Waiting for unfinished jobs....
AR lib/freebasic/linux-x86_64/libfbmt.a

The following command was used to run the build:

make -j5 bootstrap CFLAGS="-DDISABLE_X11 -DDISABLE_GPM -DDISABLE_FFI -DDISABLE_OPENGL"

I suspect this is a race condition issue, because the issue disappears when the number of make jobs is restricted to 1:

make -j1 bootstrap CFLAGS="-DDISABLE_X11 -DDISABLE_GPM -DDISABLE_FFI -DDISABLE_OPENGL"

On my system, this issue is only present when making bootstrap; making all (i.e. compiling fbc normally using an existing fbc) completes correctly even with multiple make jobs.

Fixed in pull request #132. Thanks.
