There must be something wrong with your machine if this happens.

arch/sparc/configs/sparc64_defconfig builds in about 5 or 6 minutes
at "-j32" on my Niagara-T1 based boxes.

My Niagara-T2 box at "-j64" can build that in just over a minute.
An allmodconfig takes ~22minutes, and almost half of that is the
single-threaded work of linking the final vmlinux image and running
modpost on thousands of modules.
