[Buildroot] [PATCH 1/1] minizip: needs __register_atfork

[Fabrice Fontaine]

The following error is raised:

[100%] Linking C executable minizip
/home/peko/autobuild/instance-0/output/host/m68k-buildroot-uclinux-uclibc/sysroot/usr/lib/libbsd.a(arc4random.o): In function `_rs_init.part.1':
arc4random.c:(.text+0xaa): undefined reference to `__register_atfork'
collect2: error: ld returned 1 exit status

As specified in openssl/Config.in, uClibc on noMMU doesn't provide
__register_atfork() so add this dependency on minizip

It should be noted that technically, this dependency comes from libbsd.
Indeed _ARC4_ATFORK is defined to be __register_atfork if __GLIBC__ is
defined and to pthread_atfork otherwise (see src/arc4random_linux.h)

So perhaps this dependency should be added to libbsd and to hcitop from
bluez-alsa (netcat-openbsd depends on glibc)

Fixes:
