following up on my own post, i decided to scan the entire oe-core
tree:
$ grep -r "_append +=" *
meta/recipes-support/gmp/gmp_5.0.4.bb:SRC_URI_append +=
"file://use-includedir.patch \
meta/recipes-core/eglibc/eglibc-package.inc:FILES_${PN}-dev_append +=
"${bindir}/rpcgen ${libdir}/*_nonshared.a \
meta/recipes-core/eglibc/eglibc-package.inc:FILES_${PN}-staticdev_append +=
"${libdir}/*.a ${base_libdir}/*.a"
meta/recipes-graphics/xorg-lib/libxp_1.0.1.bb:CFLAGS_append += " -I
${S}/include/X11/XprintUtil -I ${S}/include/X11/extensions"
$
and i thought i'd look for another pattern as well:
$ grep -r "_append_.*+=" *
meta/recipes-graphics/tslib/tslib_1.0.bb:SRC_URI_append_qemumips += "
file://32bitBE-support.patch"
meta/recipes-graphics/tslib/tslib_1.0.bb:SRC_URI_append_qemuppc += "
file://32bitBE-support.patch"
meta/recipes-sato/leafpad/leafpad_0.8.18.1.bb:SRC_URI_append_poky += "
file://owl-menu.patch;apply=yes "
$
of course, if all of the above is perfectly valid, i'm going to be
embarrassed.
