From: Pavan Nikhilesh <pbhagavat...@marvell.com>
Pmdinfogen is always compiled with host gcc.
If host gcc version is lessthan 7 and target gcc is greaterthan 7
pmdinfogen fails to compile due to unsupported cflags.
This patch removes unsupported host cflags when the above condition is
met.
Fixes: 98b0fdb0ffc6 ("pmdinfogen: add buildtools and pmdinfogen utility")
