convert ./configure from makefile syntax to plain shell syntax

In Makefiles, $ needs to be escaped into $$, and it is not possible
to have multiple commands without using ;\

Theses are removed, but the $$.mk is still kept, as in shell $$ is
the current PID and $$.mk expanding to something like 38742.mk is
a normal behavior.
