deriveConstants: no objdump program given (OpenBSD)

Building HEAD on OpenBSD 6.1 fails with:

inplace/bin/deriveConstants --gen-header -o includes/dist-derivedconstants/header/DerivedConstants.h --tmpdir includes/dist-derivedconstants/header/ --gcc-program "gcc" --gcc-flag -W
all --gcc-flag -std=gnu99 --gcc-flag -fno-stack-protector --gcc-flag -Iincludes --gcc-flag -Iincludes/dist --gcc-flag -Iincludes/dist-derivedconstants/header --gcc-flag -Iincludes/di
st-ghcconstants/header --gcc-flag -Irts --gcc-flag -fcommon --nm-program "nm" --target-os "openbsd"
deriveConstants: no objdump program given

This can be fixed in configure.ac (see attached patch).
