Subject: devtools: fix check of ccache for meson build
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=54a88d1b16303bcb923773293ceb71d8c19a6403

devtools: fix check of ccache for meson build

The meson build test fails if ccache is not available.
The use of ccache must be optional.
And if used, the compiler to check is the last word of $CC.

Fixes: e0ae780e6569 ("devtools: test compiler availability only once")
