[Chicken-users] A fix for parallel build (gmake -j)

[Vitaly Magerya]

Hi, folks. When I try to run a parallel build of chicken 4.7.0 via:

   gmake -j4 PLATFORM=bsd

... it eventually fails saying this:

> gcc  -shared -Wl,-soname,libchicken.so \
>   -o libchicken.so library.o eval.o data-structures.o ports.o files.o 
> extras.o lolevel.o utils.o tcp.o srfi-1.o srfi-4.o srfi-13.o srfi-14.o

The problems seems to arise because some libraries are being built
before libchicken.so when "gmake -j" is used.

Anyway, here's a quick fix for this issue:

(I'm not sure PRIMARY_LIBCHICKEN is the right thing to use here though).

So, if you folks think this is sensible, then please commit it.
