[OE-core] Pango multilib issue

[Zhai, Edwin]

RP,

I have found one common issues for multilib when system config file differ 
between multilibs.

https://bugzilla.yoctoproject.org/show_bug.cgi?id=2356
This bug caused by modules mechanism in pango:

pango utils, pango-querymodules produce a system config file to indicate where
to find the modules when 1st boot, like /usr/{lib64|lib}/pango/1.6.0/modules/
for {x86-64|lib32}-pango respectively. 

When installing lib32-pango on sato-image-qemux86-64, lib32 version of
pango-querymodules override x86-64 version and produce a system config file
with path for lib32 version of modules. Then x86-64 matchbox-desktop failed to
open these modules and loaded corrupted fonts.

To resolve this conflict, one possible solution is put the config file and 
binary under different dir: $LIBDIR for config file, and 
/usr/{libexec|lib64exec} for config binary(or create different dir under 
/usr/bin/ for different multilib)

Any comments for this?

Thanks,
