Instead of this (and the related minizip change), what about moving the:

	depends on !(BR2_TOOLCHAIN_USES_UCLIBC && !BR2_USE_MMU)

to BR2_PACKAGE_LIBBSD_ARCH_SUPPORTS ?

Since we don't display a comment about it, it is effectively treated
like an architecture dependency, and it kind of is, since anyway the
only C library that supports noMMU systems is uClibc (yes, musl
supports noMMU on SH2, but we don't support that in Buildroot).

Having this dependency directly in BR2_PACKAGE_LIBBSD_ARCH_SUPPORTS
avoid the need to replicate it to all reverse dependencies of libbsd
(and therefore the reverse dependencies should be changed as well).

Best regards,

Thomas
