When building with clang (11.0,--buildtype=debug), eal_lcore.c
produces a -Wformat-nonliteral warning from the vfprintf call
in log_early.

Disable the warning for log_early when building with clang.
MinGW does not seem to detect the warning.

When building with clang (11.0,--buildtype=debug), eal_lcore.c
produces a -Wformat-nonliteral warning from the vfprintf call
in log_early.

Add __rte_format_printf annotation.
