I don't know about configure/make. Cmake should work.

It takes 8 seconds to statically link a debug-mode JITter with all
optimization passes and bitwriter on a Linux 64bits 2.4 GHz Intel
Q6600. Generates a 114 MB file. If yours requires much more time, check
that you are using a recent version of binutils.

A release mode build links much faster.
