Well, setting gb_FULLDEPS to the empty string should do the trick
unless it broke in the meantime. While on gcc deps would still be
generated, they would be ignored by the build system, thus making the
build quite a bit faster. Actually on Linux it might make sense to
ignore deps on a build from scratch and only read them on incremental
builds, but I fear that might be a bit to fragile to distill in some
automagic.

Best,

Bjoern
