[oe] [PATCH] autotools.bbclass: enhanced oe_runconf() to accept quoted arguments

[Enrico Scholz]

This patch allows to pass quoted strings in EXTRA_OECONF.  E.g. with
this patch, it is possible to do

| EXTRA_OECONF = "--with-build-cflags='${BUILD_CFLAGS}'"

where 'BUILD_CFLAGS' contains multiple, whitespace separated arguments.

Such flags can be also passed to oe_runconf() directly:

| oe_runconf --with-build-cflags="${BUILD_CFLAGS}"

This patch might create incompatibilities for recipes which workaround the
current limitations.

As a sideeffect, 'set -x' debug output is now much nicer because
superflous whitespaces in the configure call are removed.
