There is an error when linking static EAL library with an application:
eal_alarm.c:(.text+0xd7): undefined reference to `clock_gettime'
eal_alarm.c:(.text+0x20f): undefined reference to `clock_gettime'
eal_timer.c:(.text+0x108): undefined reference to `clock_gettime'
eal_timer.c:(.text+0x146): undefined reference to `clock_gettime'
The function clock_gettime() is in librt for old glibc.
Fixes: 281948b4753e ("mk: fix missing librt dependencies")
