Any GNU/Linux environment with awk uninstalled.
>Description:
During configure:
...
checking for GNU C library... yes
checking for mawk... no           
checking for gawk... no       
checking for nawk... no       
checking for awk... no     
checking whether ln works... yes
...
Still, configure continues.  Build fails with unfriendly message:
if [ -f ranlib ] || ( [ cris-axis-linux-gnu = cris-axis-linux-gnu ] && [ -f /usr/bin/ranlib -o -f /b
  ranlib ./libgcc_eh.a ; \                                                                          
else true; fi;

when attempting to use $AWK while building the linker map for libgcc.so
>How-To-Repeat:
Uninstall all awk (gawk, nawk, awk).
Configure.  Attempt bootstrap.
>Fix:
Check $AWK in gcc/configure.in after AC_PROG_AWK call;
bail out with error message if empty.
(At user level: install gawk. :-)
