multilibs are a gcc feature to build libs multiple times using different
sets of compilation flags for different sub-targets, resulting into
libraries being optimized for different sub-targets.
Configuring the RTEMS source tree with --enable-multilib builds the
cpukit multilib'ed, ie. one time each for each multilib-sub-target of
gcc.

I don't know what you are doing, but all rtems-gcc's on ftp.rtems.com
have been built with multilibs enabled.
