Here is the output
(the actual line number in the prev mail was a typo the actual line
number is 95)

Moreover if I remove the option -mthumb it works.

Again it tries to build the multilib with --enable-multilib=no.
Here is the configure script that I used.

../egcs-20000717/configure --prefix=/home/jbrahma/local
--target=arm-wrs-vxworks \
--with-newlib --disable-biendian --enable-languages="c c++"
--enable-multilib=no \
--with-cpu=strongarm110
