problem with bootstrap-lean

[Kate Hedstrom]

"make bootstrap-lean" gets through building stages 1, 2, 3 and "make
compare".  It then goes to build the f/runtime libraries again and
fails with:

loading site script /dev/null
loading cache ./config.cache
checking for gcc... (cached) stage2/xgcc -Bstage2/
checking whether the C compiler (stage2/xgcc -Bstage2/ -g -O2 ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.
*** Error code 1

Stop.

Note that the stage2 compiler has been deleted at this point.
