More detail:

NetBSD/sh3 decided to use softfloat by default.  Its libc builds
libgcc-compatible softfloat functions unconditionally (see [1] including
softfloat/Makefile.inc).  For libgcc, the intention was to *not* build any
softfloat functions. [2]  But the misconfiguration makes NetBSD/sh3 build
fp-bit.c / dp-bit.c. [3]

The patch I posted makes libgcc to be built as intended.  I've not considered
backward compatibility or any possible problem the correction will cause.
