If no enable_drivers option is passed, the default is to build
the drivers list by calling list-dir-globs.py.
But if no Python interpreter is installed, no error is reported
and all drivers end up being disabled.
Example on a minimal FreeBSD VM:
dpdk@freebsd:~/dpdk $ meson setup build
...
drivers:
common/cpt: not in enabled drivers build config
common/dpaax: not in enabled drivers build config
common/iavf: not in enabled drivers build config
common/mvep: not in enabled drivers build config
common/octeontx: not in enabled drivers build config
common/octeontx2: not in enabled drivers build config
bus/dpaa: not in enabled drivers build config
bus/fslmc: not in enabled drivers build config
...
dpdk@freebsd:~/dpdk $ cd drivers/
dpdk@freebsd:~/dpdk/drivers $ ~/dpdk/buildtools/list-dir-globs.py */*
env: python3: No such file or directory
Rely on meson internal interpreter.
Check return code when calling this script.
