Yes, the Makefile sets CC CFLAGS LDFLAGS excplicitly, so make doesn't
inherit them from the environment variables, because OE doesn't pass the -e
make flag anymore. https://www.gnu.org/software/make/manual/html_node/Enviro
nment.html#Environment

It doesn't respect CPPFLAGS, but an alternative would be:

EXTRA_OEMAKE = "\
    DIET= \
    DEBUG=nostrip \
    -e \
"
CFLAGS_append = " -I${STAGING_INCDIR}/libowfat"

I have no preference either way, but my original version makes it more
obvious what we're after.

Using -D that'd still need two calls, as multiple files are being copied and
-D only allows you to specify one destination (I think). Not really gaining
anything here. In addition, you have to specify the source filename multiple
times (in src and destination).
This:
    install -d -m0755 ${D}${mandir}/man1
    install -m0644 ncp.1 npush.1 ${D}${mandir}/man1
vs.
    install -D -m0644 ncp.1 ${D}${mandir}/man1/ncp.1
    install -D -m0644 npush.1 ${D}${mandir}/man1/npush.1
