[dpdk-dev] [PATCH] devtools: select targets in build test

[David Marchand <david.marchand@redhat.com>]

When a target compilation is broken, one way to skip the target is to
uninstall the associated toolchain.
But it is not always possible and you end up with hacking the script to
avoid this target until a fix is ready.

It is also often quicker to check a fix on a failing target before
checking compilation on all targets.

Introduce a variable to select targets.

Example:
$ DPDK_BUILD_TEST_TARGETS=build-x86-mingw \
    ./devtools/test-meson-builds.sh
ninja: Entering directory `/home/dmarchan/builds/build-x86-mingw'
[...]
Found ninja-1.10.1 at /usr/bin/ninja
[19/19] Linking target examples/dpdk-helloworld.exe
