seems to not support arm

also remove unused patches

from upstream: http://bugzilla.abisource.com/show_bug.cgi?id=13582

lcms was upgraded to lcms2 so upgrade accordingly. this should also
fix the build failure on arm edge.

SSE is intel only, but still needs to be explicitly disabled
for audacity to compile on arm

valgrind supports armv7+, but we build for armv6 so valgrind
refuses to compile. for the time being disable it.

the outdated config did not build, so no pkgrel bump needed.

-reduce-relocations is not supported and causes build failure.
pkgrel does not need bump as only non-building armhf is affected.

fixes #3555

This reverts commit 718468ec.

The upgrade did not work out, just disable on arm.

makekit does not seem to support arm architecture currently.

update execinfo patch to completely remove any attempts to
do backtrace(). the code would insisted trying to use backtrace()
on arm. imitating backtrace() is generally bad practice security
wise. and this also fixes jack to produce core dumps.

arm has only limited support for __builtin_return_address() due
to calling convention. disable the backtrace() emulation on arm.

there's inline assembly for x86/x86_64 in several places.

pass in the fp abi we use. no affect for non-arm platforms, and as
this caused build failure, no pkgrel bump is needed.

xmlcatalog was changed, and XML_CATALOG_FILES needs to be now
set to empty string when modifying non-default catalog.
