Apparently it was not:
$ /usr/nb/tools/bin/shle--netbsdelf-gcc -dumpspecs | grep -e -lgcc
$ /usr/nb3/tools/bin/shle--netbsdelf-gcc -dumpspecs | grep -e -lgcc
If linking -lgcc_pic into shlibs is ok, we won't need a special
library, just move __udivsi3 &c into libgcc and mark the .hidden.
PS: While we are at the topic of libc vs. libgcc why do we have our
own softfloat in libc and also have gcc's softfloat in libgcc?
