In the Config.in file of package foo, it often happens that there are other
symbols besides BR2_PACKAGE_FOO. Typically, these symbols only make sense
when foo itself is enabled. There are two ways to express this: with
depends on BR2_PACKAGE_FOO
in each extra symbol, or with
if BR2_PACKAGE_FOO
...
endif
around the entire set of extra symbols.
The if/endif approach avoids the repetition of 'depends on' statements on
multiple symbols, so this is clearly preferred. But even when there is only
one extra symbol, if/endif is a more logical choice:
- it is future-proof for when extra symbols are added
- it allows to have just one strategy instead of two (less confusion)
This patch modifies the Config.in files accordingly.

OpenPGM builds incorrectly on AVR32 with gcc-4.2.2-avr32-2.1.5.
Since it is presumed to be the only GCC version used by Buildroot
for AVR32, this patch disables openpgm for all cases when AVR32
is selected as the target architecture, including when a toolchain
is downloaded or preinstalled (this is what Buildroot autobuilders
do).

openpgm doesn't build correctly on AVR32 using
gcc-4.2.2-avr32-2.1.5 toolchain: it is configured to call
intrinsic atomic functions not provided by the toolchain,
so they are propagated as unresolved external symbols in the
built openpgm libraries. This breaks programs that try to link
openpgm, because they do not know where to get those either. For
instance, it breaks building zeromq tests when PGM support is
selected.
This commit disables openpgm on AVR32 due to apparent absence of
interest in this package on that architecture and it breaking too
many test builds.

The zeromq package was recently bumped from version 2.2.0 to version 3.2.2,
which has introduced a requirement for IPv6 support in the toolchain. At
present, IPv6 support is mandatory in zeromq: there is no configuration option
to enable/disable the feature.

This adds support for Pragmatic General Multicast protocol on raw
IP (PGM, RFC 3208) or UDP frames (EPGM) for use as zeromq reliable
multicast transport. The library relies on openpgm package to
implement the protocol itself.
