arm--netbsd floating point config change.

[Krister Walfridsson]

Some testsuite tests fail for arm--netbsd because __unorddf2 is not found
during linking. The patch below adds it to libgcc.a in the same way as
is already done for the rest of the arm targets.

Bootstrapped and checked on arm-unknown-netbsd1.5Y.

	* config/arm/t-netbsd (FPBIT): New.  Added so that __unorddf2 is
	included in libgcc.a.
	(DPBIT): Likewise.
	(dp-bit.c): Likewise.
	(fp-bit.c): Likewise.
