After reconfiguring, the value of slibdir changes from ${exec_prefix}/lib32 or
${exec_prefix}/lib64 to ${exec_prefix}/lib.

This is because the code that sets libdir is only executed if libc_cv_slibdir
is unset (this is to provide an override mechanism for subtargets).  If the
value of libc_cv_slibdir is read from the config cache the value of libdir is
never adjusted.  Or:

  $ rm config.cache 
  $ ~/src/glibc/configure --host=mips64-unknown-linux-gnu --build=i686-linux
--prefix=/usr --cache-file=config.cache &>/dev/null
  $ grep libdir config.make 
  libdir = ${exec_prefix}/lib32
  slibdir = /lib32
  $ ~/src/glibc/configure --host=mips64-unknown-linux-gnu --build=i686-linux
--prefix=/usr --cache-file=config.cache &>/dev/null
  $ grep libdir config.make 
  libdir = ${exec_prefix}/lib
  slibdir = /lib32

With the current logic, either both libdir and slibdir should be cached or
neither.
