This makes "make menuconfig" also work on systems where ncurses is not
installed in a standard location (such as on NixOS).
This patch changes ccflags() so that it tries pkg-config first, and only
if pkg-config fails does it go back to the fallback/manual checks. This
is the same algorithm that ldflags() already uses.

Applied to kbuild.git#kbuild, thanks.

check-lxdialog.sh has functions for finding ncurses linker and compiler
flags; ldflags() and ccflags().
ldflags() tries to get linker flags from pkg-config and has a fallback
if pkg-config fails. But ccflags() currently doesn't use pkg-config at
all, instead it does manual checks like this:
if [ -f /usr/include/ncursesw/curses.h ]; then
echo '-I/usr/include/ncursesw -DCURSES_LOC="<curses.h>"'
echo ' -DNCURSES_WIDECHAR=1'
elif [ -f /usr/include/ncurses/ncurses.h ]; then
echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses.h>"'
[...]
This patch changes ccflags() so that it also tries pkg-config first, and
only if pkg-config fails does it go back to the fallback/manual checks.
This makes ldflags()/ccflags() symmetric (both try to use pkg-config
before falling back to manual checks) and has the nice side-effect of
making "make menuconfig" work on systems where ncurses is not installed
in a standard location (such as on NixOS).
