arch: sparc: Add leon3 cpu type and remove sparc{s,h}fleon{,v8}

There is support for -mcpu=leon3 from gcc 4.8.3. Use this for LEON systems
instead of the non-mainline targets sparcsfleon, sparchfleon, sparcsfleonv8, and
sparchfleonv8.

[Thomas: add Config.in.legacy handling for the removed options.]

gcc: remove version 4.4.x

That gcc series is old and is not used as the default version for
any of the architectures we support, so this commit gets rid of it.

[Thomas: move the Config.in.legacy option at the right location.]

shairport-sync: needs toolchain with NPTL

Also remove the comment attributing threads dependency to alsa-lib, since
shairport-sync itself uses pthreads.

tcpdump: use libpcap shared library

Currently the tcpdump configure script finds libpcap.a in
output/build/libpcap-[version]. This check is hard coded in aclocal.m4. Add a
patch to optionally ignore local libpcap so that the system shared library
version is found instead. This reduces the tcpdump binary size in a few 100KB.

package/dovecot: New package

[Thomas:
 - slightly adjust the prompt of options in the Config.in file
 - fix license: it's just LGPLv2.1, no exceptions. Parts of the code
   are under public domain, or under the MIT license, but the
   combination is under LGPLv2.1.
 - rewrap one comment in the .mk file.]

lame: Disable debug symbols for Aarch64 and MIPS

Building lame with debug symbols needs the following macros to be
defined: _FPU_MASK_IM, _FPU_MASK_ZM, _FPU_MASK_OM.
So, if BR2_ENABLE_DEBUG is selected, then we have to force lame to be
built without debug symbols for Aarch64 and MIPS because these
architectures don't have those macros defined.
