Summary:                    sort (at least with CONFIG_FEATURE_SORT_BIG=y) needs
libm
Description: 
build fails with undefined symbols __isnsn and __isinf in sort.o
since I unconfigured dc (which has 'needlibm-$(CONFIG_DC) := y' )

this *may* only occur when CONFIG_FEATURE_SORT_BIG=y

This is uClibc specific.
With glibc, you do not need libm for isinf etc.

Compile with CFLAGS_EXTRA="-Wl,lm" when you use uClibc and you have no
applet configured which pulls in libm for you.

Alternatively fix the big sort to play nice with uClibc.
