Today I took yesterday's CVS sources (the same I used for the Solaris
builds), hacked the i586-linux-gnulibc1 configuration to be

  a. multilib'ed for mcpu=pentium/mcpu=i486
  b. using LIBGCC=stmp-multilib
  c. using fixinc.svr4 for fixing include files
  d. and defining STMP_FIXPROTO to be stmp-fixproto

Using this tree I wasn't able to reproduce your problem, neither when
running gmake sequentially nor when giving `-j 4' to GNU make. It
looks to me, like you still have the prior patches applied. You should 
update gcc/Makefile.in from the current CVS sources.

Please tell me, if this works for you.
