problems building mipsel-none-elf gcc libgcc

[Wojciech Puchar]

for a microcontroller.

configured with

../../orig/gcc-9.3.0/configure --target=$TARGET --prefix=$PREFIX --with-gmp=$TMPB --with-mpfr=$TMPB --with-mpc=$TMPB --disable-werror --disable-nls --with-dwarf2 --without-newlib --disable-threads --disable-libssp --disable-libgomp --disable-libmudflap --without-interwork --enable-languages="c"

gmake all-gcc and install-gcc works fine

gmake all-target-libgcc doesn't work

after some work it exits with error:

how to fix it.

i can write a working program for a microcontroler with this gcc but until 
i will not do something more complex that needs libgcc

please help
