First, the comment is now not accurate anymore. It should also say
something about the architectures where it is not available.

Then the logic below says that PACKAGE_NETSURF depends on "!STATIC_LIBS
*AND* NETSURF_ARCH_SUPPORT". The dependency of the comment above is
inverted, so I think this rather should be:

       depends on BR2_STATIC_LIBS || !BR2_PACKAGE_NETSURF_ARCH_SUPPORTS

?
