gconv-modules.cache invalid for 32bit apps on multilib

[Elan Ruusamäe]

launching skype gives out errors:

  QIconvCodec::convertFromUnicode: using ASCII for conversion, iconv_open failed
  QIconvCodec::convertToUnicode: using ASCII for conversion, iconv_open failed

even having 32bit iconv package installed [1].
the problem seems to came from packaged gconv-modules.cache file [2], as the strace -ff -eopen shows:

open("/tmp/B.bb679c/glibc-2.9-root-builder/usr/lib/gconv/UTF-16.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/tmp/B.bb679c/glibc-2.9-root-builder/usr/lib/gconv/UTF-16.so", O_RDONLY) = -1 ENOENT (No such file or directory)

however, previosly the cache was built by invoking iconvconfig, but that won't update 32bit iconv modules path as the packaged one is for 64bit arch, which defaults to writing /usr/lib64/gconv:

# rm -f /usr/lib/gconv/gconv-modules.cache
# iconvconfig
# ls -ld /usr/lib/gconv/gconv-modules.cache
ls: cannot access /usr/lib/gconv/gconv-modules.cache: No such file or directory

fix commited:
http://cvs.pld-linux.org/cgi-bin/cvsweb.cgi/SPECS/glibc.spec.diff?r1=1.805;r2=1.806

however running iconvconfig in %post of 32bit library is void, as it updates 64bit modules path.
is there point at all running it in %post?

no %post for iconv:
