This reverts commit 8eaafb7. Preparing to switch to older versions of gmp and gnutls.
Should be compatible back to webOS 3.0. LG is unwilling to use later versions of gnutls because some parts were relicensed under the GPLv3. (However, only the tools and OpenSSL compatibility layer are GPLv3, and LG does not ship those. The issue may be dependencies such as nettle and gmp.) gnutls 2.x (libgnutls.so.26): - webOS 1, 2: 2.12.23 gnutls 3.x (libgnutls.so.28): - webOS 3.x: 3.3.5 - webOS 4.x: 3.3.27 - webOS 5-8: 3.3.30

The primary goal of this PR is to stop programs built with br-nc4 from requiring a separate copy of GMP. The other changes were consequences of the GMP version change.
It appears that LG is unwilling to update several packages because they're afraid of GPLv3-licensed software (see meta-gplv2).
GMP 4.2.1 has been used on every version of webOS so far (and probably NetCast, since it was released in 2006). Rolling back to this version allows us to use the
libgmp.so.3present on webOS.GnuTLS 3.3.30 should work for webOS 8 back through 3.0, as 3.3.x versions with a soname of
libgnutls.so.28have been used since then. GnuTLS 2.12.23 (with the sonamelibgnutls.so.26) was used on webOS 1 and 2. If GnuTLS is present on NetCast, it's probably also a 2.x version.Nettle is rather closely coupled with both GMP and GnuTLS. It was reverted to 2.7.1, which is the version on webOS 3.0+. It's not present on webOS 1 or 2 (which probably use the libgcrypt backend for GnuTLS 2.x).
Buildroot also builds these packages for the host. I made separate
webos-packages for GnuTLS and GMP. It still seems to work without a separate package for Nettle, though. These packages are intended to replace the libraries built for the target without affecting the host build.Currently, these
webos-packages are automatically selected whenBR2_WEBOS_COMPATis enabled. I'm sure there is a better way to do this.
