Hi, Saul:

I did some investigations about this issue, it should be a regression 
introduced by commit 91c0f9e3: util-linux: move libraries to 
base_libdir. It tried to transfer "--libdir=${base_libdir}" to 
EXTRA_OECONF at configure status, which conflicted with following code 
in configure.ac:
.........
case $libdir in
  ${exec_prefix}/* | ${prefix}/* | /usr/*)
     usrlib_execdir=$libdir ;;
  *)
     usrlib_execdir='${exec_prefix}'$libdir ;;
esac
AC_SUBST([usrlib_execdir])
........

It resulted a invalid usrlib_execdir, and therefore caused libuuid.so 
link unreachable. This would make packages relies on uuid fail to 
compile, like e2fsprogs.

Anyway, it could be fixed by appending "--prefix=${base_prefix} 
--exec_prefix=${base_prefix}" to EXTRA_OECONF and we don't need to worry 
it, however, things go to more complicated after applied 91c0f9e3 that 
it also breaks pkgconfig, because all *.pc go to ${base_libdir} instead 
of  ${libdir} though pkg-config looks for files in explicitly fixed 
directories set by PKG_CONFIG_PATH, which in this case is: 
${STAGING_DATADIR}/pkgconfig${EXTRA_NATIVE_PKGCONFIG_PATH}, that finally 
causes other packages fail to detect libuuid by pkg-config.

Two approaches to fix this pkg-config failure, first, we could move *.pc 
to ${libdir} at do_intall stage, and the other, modify PKG_CONFIG_PATH, 
adding ${libdir}/pkgconfig into it. Which one do you prefer? Or we could 
just revert commit 91c0f9e3?

the best,
thank you
