I used this patch (not sure if still needed):

and these configure options:
CC=musl-gcc CFLAGS="-fno-stack-protector -Os -D_GNU_SOURCE" ./configure
--prefix=${PREFIX} --without-cxx --with-fallbacks=xterm
#forgot to add --enable-widec
(see github.com/idunham/src-musl if you'd like to see my full build
scripts...really, it ended up looking a lot like a pkgbuild, but
somewhat more awkward)

I've always used CXX=false for stuff like this...
The --enable-wide is because for some reason, using wchar_t instead of
char breaks the ABI.

AKA:
CPPFLAGS += -I${sysincdir}/ncurses
CFLAGS += ${CPPFLAGS} # if the makefile ignores CPPFLAGS

It doesn't seem to allow installing $sysincdir/curses.h
FYI: pdcurses may also be an option.
