Subject: fix build on m68k with uclibc
X-Git-Tag: suricata-5.0.0-rc1~118
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9b05db7db0c3ed4647adbe763f77a5f61b6aefe1;p=thirdparty%2Fsuricata.git

fix build on m68k with uclibc

uclibc on m68k defines _POSIX_SPIN_LOCKS but does not define
pthread_spin_unlock so check for this function before using
pthread_spin_xxx functions

Fixes:
