Subject: devtools: allow warnings in ABI reference build
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=ef5391b7658b0ce9c0626bf3ecdc3db600e44c0e

devtools: allow warnings in ABI reference build

There is no point in forcing warning-free compilation when building
an ABI reference. It is only preventing from compiling ABI reference
of old releases with recent compilers.

Note: DPDK 20.02 is built (with warnings) by GCC 10 if using -fcommon.
