[PATCH] tools: Fix mqueue Makefile compile linking order

From: Shuah Khan
Date: Tue Jun 24 2014 - 21:59:53 EST


Makefile compile linking order is incorrect causing the compile
to fail not finding librt symbols.

/tmp/cceTqwFh.o: In function `test_queue_fail':
mq_open_tests.c:(.text+0x6b): undefined reference to `mq_open'
mq_open_tests.c:(.text+0x80): undefined reference to `mq_getattr'
mq_open_tests.c:(.text+0xa2): undefined reference to `mq_close'
mq_open_tests.c:(.text+0xcf): undefined reference to `mq_unlink'
/tmp/cceTqwFh.o: In function `test_queue.constprop.6':
mq_open_tests.c:(.text+0x15a): undefined reference to `mq_open'
mq_open_tests.c:(.text+0x16f): undefined reference to `mq_getattr'
mq_open_tests.c:(.text+0x195): undefined reference to `mq_close'
mq_open_tests.c:(.text+0x1c2): undefined reference to `mq_unlink'
/tmp/cceTqwFh.o: In function `shutdown.part.0':
mq_open_tests.c:(.text.unlikely+0x5b): undefined reference to `mq_close'
mq_open_tests.c:(.text.unlikely+0x7a): undefined reference to `mq_unlink'
collect2: error: ld returned 1 exit status
make: *** [all] Error 1
