removing -no-cpp-precomp flag ?

[Bill Allombert <allomber@math.u-bordeaux.fr>]

Hello PARI-dev

I would like to propose the patch below that remove the -no-cpp-precomp
flag on Darwin.

This flag does not seem necessary and is not reckognized by non-Apple
gcc build.

Is this flag required by some flavours of Mac OS X ?

Cheers,
Bill
