The ENABLE_WIDEC variable can be used to disable ncurses wide character support
when your C library doesn't support it. Currently, the do_configure step
configures for both narrow and wide characters regardless and only checks
ENABLE_WIDEC during compilation. This leads to QA failures with host
contamination during configure if the C library doesn't support wide characters.
Refactor do_configure with a new ncurses_configure helper function and only
configure for wide character support if ENABLE_WIDEC is true.
Ensure that configure errors are propogated back through to do_configure.
Tested with ENABLE_WIDEC as true and false via an ncurses bbappend on i586,
including basic error injection.
