Update nios2, sparc32 localplt.data for difftime changes (bug 24023).

Browse Source 
The recent difftime changes introduced localplt test failures on nios2
and sparc32, two configurations where some soft-fp functions are
defined in / exported from libc.so, and where the difftime changes
affected the particular set of floating-point operations used in
libc.so.  This patch adds those functions to localplt.data, alongside
other such functions already there.  (In the sparc32 case, and more
generally on any platform where long double is a software
floating-point type, it would probably be more efficient to avoid
using long double at all in difftime, but that's a pre-existing
issue.)

Tested with build-many-glibcs.py for its nios2 and sparcv9
configurations.

	[BZ #24023]
	* sysdeps/unix/sysv/linux/nios2/localplt.data: Allow __floatundidf
	PLT reference in libc.so.
	* sysdeps/unix/sysv/linux/sparc/sparc32/localplt.data: Allow
	_Q_lltoq and _Q_qtod PLT references in libc.so.
