This patch fixes two Qtopia build issues, encountered while trying to
use system implementation of zlib, freetype, jpeg and libpng :
* The build process doesn't look in $(STAGING_DIR)/usr/include for
includes and $(STAGING_DIR)/usr/lib. Same problem as the patch
currently floating around adding LDFLAGS to TARGET_CONFIGURE_OPTS,
but as Qtopia doesn't use TARGET_CONFIGURE_OPTS, we need a specific
fix here. So we use the -I and -L options of Qtopia's configure
script.
* The build process doesn't use pkg-config to get the header path for
Freetype headers (located in $(STAGING_DIR)/usr/include/freetype2
and not directly in $(STAGING_DIR)/usr/include/). There was already
a fix for this, consisting in adding $(FREETYPE_DIR)/include to the
-I path of Qtopia's configure. This patch modifies this fix to use
$(STAGING_DIR)/usr/include/freetype2 instead, which looks more
coherent with how all the packages are built (using $(STAGING_DIR)
as the reference to get headers and libraries).

Extend the regexp to match spaces and also tabs to replace the qmake
variables with the proper buildroot values. Also use TARGET_AR and
TARGET_STRIP instead of using TARGET_CROSS and set a variable for
qmake.conf to shorten the command line.

When cross compiling, Qt sets PKG_CONFIG in its own configure script to
an empty string. That leads to not using pkg-config. To avoid that, use
the configure option -force-pkg-config. Also set environment variables
for pkg-config defined in TARGET_CONFIGURE_OPTS.
