Description of problem:
On x86_64 system, m17n-lib modules are installed under /usr/lib64/m17n/1.0.  However pkg-config scripts hard-code the location as /usr/lib/m17n/1.0.

Version-Release number of selected component (if applicable):
m17n-lib-devel-1.6.2-1.fc14

How reproducible:
always

Steps to Reproduce:
1.pkg-config --variable=moduledir m17n-shell
2.
3.
  
Actual results:
/usr/lib/m17n/1.0

Expected results:
/usr/lib64/m17n/1.0

Additional info:
Possible solution would be to use ${libdir} instead of ${exec_prefix}/lib in *.pc.

BTW, it seems that /usr/lib{,64}/m17n is not owned by any package:
 $ rpm -qf /usr/lib64/m17n
 file /usr/lib64/m17n is not owned by any package
while  /usr/lib64/m17n/1.0/libmimx-anthy.so is owned by m17n-lib-anthy:
 $ rpm -qf /usr/lib64/m17n/1.0/libmimx-anthy.so
 m17n-lib-anthy-1.6.2-1.fc14.x86_64
