[PATCH v2 1/4] configure: Use discovered make for in-source build

[Roman Bolshakov]

A recursive make is invoked if in-source build is used but $(MAKE) is
the same as the one used in the original make invocation.

Some platforms have preference to use gmake, or a make passed as an
option to "configure". Honor the choice.
