to LIBS resulting in the following build failure with zeromq:

/home/buildroot/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/i586-buildroot-linux-musl/9.3.0/../../../../i586-buildroot-linux-musl/bin/ld: /home/buildroot/instance-0/output-1/host/i586-buildroot-linux-musl/sysroot/usr/lib32/libunwind.so.8: undefined reference to `setcontext'
