i just had this problem myself.  it indicates that the libs for your abi (n64
in this case) are not installed.  look in /usr/lib64.  you probably won't find
libm.{so,a}.  if not, install the compiler_eoe.sw64.* modules.

the egcs configure should probably check for this library since it is implicitly
required by g++, in all abi's, even if not explicitly requested by the user.
i was blithely unaware of this during my build of 1.1.2 until i (or more
accurately, one of my irate users) actually tried to *use* the g++ binary.
it shouldn't necessarily be fatal to configure, since the build works fine
without it, and if you only need gcc and never g++, it doesn't matter.
but somehow its absence should be brought to the builder's attention.
the above error message will be very opaque to a sysadmin who has
not had extensive experience in dealing with multilib problems on sgi
(which btw is why i now spell it sgigh... the g is silent...).
