[Buildroot] [PATCH 1/1] package/zeromq: disable libbsd on static build

[Fabrice Fontaine]

Static linking with libbsd fails because of multiple definition of the
strlcpy symbol. uClibc optionally provides these symbols.

So disable libbsd on zeromq when linking statically to avoid the
following build failure with bitcoin and zeromq:

  CXXLD    bitcoind
/tmp/instance-1/output-1/host/lib/gcc/powerpc-buildroot-linux-uclibc/9.3.0/../../../../powerpc-buildroot-linux-uclibc/bin/ld: /tmp/instance-1/output-1/host/powerpc-buildroot-linux-uclibc/sysroot/usr/lib//libc.a(strlcpy.os): in function `__GI_strlcpy':
strlcpy.c:(.text+0x0): multiple definition of `strlcpy'; /tmp/instance-1/output-1/host/powerpc-buildroot-linux-uclibc/sysroot/usr/lib/libbsd.a(strlcpy.o):strlcpy.c:(.text+0x0): first defined here

Fixes:
