gmake options for building configurations

An option for gmake can be thought of as an argument which tells it how it should make a target. Note that the final result is always the same.

gmake <target> PROMPT=no

turns off all prompts from the make system.

gmake <target> SILENT=no

print the commands that gmake is executing.

gmake <target> WARN=yes

show compiler warnings during compilation.

gmake <target> FJOBS=<number>

compile in parallel, across files within each thorn.

gmake <target> TJOBS=<number>

compile in parallel, across thorns.

Note that with more modern versions of gmake, it is sufficient to pass the normal -j <number> flag to gmake to get parallel compilation.
