[PATCH 4.14 098/161] libsubcmd: Use -O0 with DEBUG=1

[Greg Kroah-Hartman]

From: James Clark <James.Clark@xxxxxxx>

[ Upstream commit 22bd8f1b5a1dd168ba4eba27cb17643a11012f5d ]

When a 'make DEBUG=1' build is done, the command parser is still built
with -O6 and is hard to step through, fix it making it use -O0 in that
case.
