commit: https://git.buildroot.net/buildroot/commit/?id=e13855c48f21eaee07a81f8b02678839be274a45
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The following error is raised by minizip:

[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 a dependency on
!(BR2_TOOLCHAIN_USES_UCLIBC && !BR2_USE_MMU) on libbsd and minizip

Don't add this dependency to netcat-opensd as it already depends on
glibc
Don't add this dependency to BR2_PACKAGE_BLUEZ_ALSA_HCITOP because
bluez-alsa already depends on BR2_USE_MMU
Concerning fwts, just update comment on BR2_USE_MMU

Fixes:
