Ouch, you're right. The configure script is currently only called
indirectly (from the Makefile) and without arguments during do_compile.

How about adding this simple do_configure function?

do_configure() {
    ${B}/configure ${EXTRA_OECONF}
}

Good point. I thought the _remove was ugly, but it didn't occur to me to
use an additional level of indirection like this.
