* -I../ofono-1.31 is included when building drivers/mbimmodem/mbim.c and then
ell.h will happily include ell/util.h from there:
# 1 "/OE/build/oe-core/tmp-glibc/work/core2-64-oe-linux/ofono/1.31-r0/recipe-sysroot/usr/include/ell/ell.h" 1 3 4
# 23 "/OE/build/oe-core/tmp-glibc/work/core2-64-oe-linux/ofono/1.31-r0/recipe-sysroot/usr/include/ell/ell.h" 3 4
# 1 "../ofono-1.31/ell/util.h" 1 3 4
# 26 "../ofono-1.31/ell/util.h" 3 4
# 1 "/OE/build/oe-core/tmp-glibc/work/core2-64-oe-linux/ofono/1.31-r0/recipe-sysroot/usr/include/string.h" 1 3 4
# 26 "/OE/build/oe-core/tmp-glibc/work/core2-64-oe-linux/ofono/1.31-r0/recipe-sysroot/usr/include/string.h" 3 4

# 27 "/OE/build/oe-core/tmp-glibc/work/core2-64-oe-linux/ofono/1.31-r0/recipe-sysroot/usr/include/string.h" 2 3 4
* and it gets more interesting because unlikely() macro was dropped from ell/util.h in:

2a682421b06e41c45098217a686157f576847021
and ofono builds from git (which doesn't bundle ell) were failing with:

while build from 1.31 tarball was passing OK, because using this older
bundled ell/util.h
delete bundled ell as we always enable external ell to make sure this
doesn't happen again and fix mbimmodem to build with ell-0.39
