Subject: devtools: split meson build helper
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d6f923ba4a458a17d1f47f41db9c0ea960bba8b5;p=dpdk.git

devtools: split meson build helper

No functional change intended, prepare for reusing this code.
The config and compilation parts are separated in helpers.
Unsetting CC is moved to the caller of the helper.
