Comment # 3 on bug 94443 from Emil Velikov

As mentioned in bug 94394, (and hinted in the error message) you should set
your PKG_CONFIG_PATH so that it points to the .pc files of the 32 bit setup.

Namely
export PKG_CONFIG_PATH=/usr/lib/pkgconfig/
./configure .....

Please, avoid touching *any* _CFLAGS/_LIBS variables. Do reopen if the
suggestion does not work as opposed to opening yet another bug.

Thank you
