MIPS soft float

I am trying to build MIPS toolchain with soft float,
without success :-(

Using crosstoll-0.35 (tried with 0.38 too) with various 
combination of flags in mipsel.dat, like:
TARGET_CFLAGS="-O2 -finline-limit=10000 -msoft-float"
GCC_EXTRA_CONFIG="--with-float=soft --nfp"

If I do:
mipsel-linux-objdump libgcc.a | grep swc1 I get:
  24:   e7b40028        swc1    $f20,40(sp)
  28:   e7b5002c        swc1    $f21,44(sp)
  3c:   e7b60030        swc1    $f22,48(sp)
  40:   e7b70034        swc1    $f23,52(sp)
  14:   e7b40028        swc1    $f20,40(sp)
  18:   e7b5002c        swc1    $f21,44(sp)

libgcca still contains FP instructions.

Has anybody successfully build MIPS SF toolchain?
