[OE-core] [PATCH 4/4] ncurses: fix beaglebone do_configure failure

[Hongxu Jia]

In configure, the option ${HOST_CC_ARCH} was removed from ${CC}:
---------------
|configure:2188: WARNING: your environment misuses the CC variable
to hold CFLAGS/CPPFLAGS options
|configure:2284: testing resulting CC: 'arm-poky-linux-gnueabi-gcc
--sysroot=tmp/work/cortexa8hf-neon-poky-linux-gnueabi/ncurses/
6.0+20161126-r0/recipe-sysroot'
---------------

While arm compiling, option "-mfloat-abi=hard" in ${HOST_CC_ARCH}
lost that caused the failure:
---------------
|tmp/work/cortexa8hf-neon-poky-linux-gnueabi/ncurses/6.0+20161126-r0/
recipe-sysroot/usr/include/gnu/stubs.h:7:29: fatal error:
gnu/stubs-soft.h: No such file or directory
| # include <gnu/stubs-soft.h>
---------------

Remove the cf_flags checking, because OE have assigned CC/CFLAGS.
