This is not autotools, libtool or anything else.
It "pretends" to be GNU configure just for ease of use in most packaging 
systems.

The *sole* requirements to build dhcpcd are:
	POSIX shell and userland for configure
	Makefile compliant build program to build it
	C-99 compiler

Heck, older verions of dhcpcd *just* had a Makefile without any 
configure and cross compiled just fine.

Luckily, the Makefile supports both CFLAGS and LDFLAGS for this, which I 
would expect to work with pretty much every build system.
In this exact case though, dhcpcd is linked with $CC (which may or may 
not be gcc)
