[dpdk-dev] [PATCH] eal: fix compilation for x86_x32-native-linuxapp-gcc

[Olivier Matz]

Compiling for dpdk x86_x32 gives the following error:

  CC eal_common_timer.o
In file included from /usr/include/sys/sysctl.h:63:0,
                 from dpdk.org/lib/librte_eal/common/eal_common_timer.c:39:
/usr/include/bits/sysctl.h:19:3: error: #error "sysctl system call is unsupported in x32 kernel"
 # error "sysctl system call is unsupported in x32 kernel"
   ^
dpdk.org/mk/internal/rte.compile-pre.mk:126: recipe for target 'eal_common_timer.o' failed
make[6]: *** [eal_common_timer.o] Error 1

Including sysctl.h was added by mistake when merging bsd and linux EAL
timer code. It can be safely removed in this file, fixing the
compilation.

Fixes: 040cf8a411 ("eal: deduplicate timer functions")
