The SYSROOT variable should not (directly) impact that. The install directory
is configured by ECM_MKSPECS_INSTALL_DIR, which usually will point to
/usr/lib/mkspecs/modules/ on Linux. For a cross-compile toolchain it will
however be additionally prefixed with separate path. But Qt and qmake will also
be configured with that prefix so those know to lookup the mkspecs dir under
that prefix. Issuing QT += <module> can then trigger the including of the
include and lib paths from the .pri generated by this code. So the case I am
trying to fix with this patch is the case where the .pri is found (so
ECM_MKSPECS_INSTALL_DIR was specified correctly) but now the libs and include
paths are pointing to /usr/{include,lib} and not to
<cross-compile-prefix>/usr/{include,lib}. Now since <cross-compile-prefix> can
differ depending on the installation dir of the tool chain it may not be
possible to know that path during compile / install time. However, we can
assume that Qt / qmake will know about the sysroot (which is the prefix
essentially). So as long qmake is configured for the cross compile our Qt
module now should be too.
