[Buildroot] [PATCH] boost: fix sparc compile

[Waldemar Brodkorb <wbx@openadk.org>]

Like for sparc64, set correct instruction set.
Patch is obsoleted by this changeset.

boost::context still does not compile. Don't know why it is
disabled for sparc/sparc64 as it contains the needed code.
Need to check on my sparc systems before enabling via a patch.
