The number of libs they bundle is quite unfortunate. But well, there's
no much you can about this besides following this bug report.

This patch unfortunately does not build here. With the following
defconfig:

BR2_arm=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-arm-full-2015.11-rc1-71-g90d1299.tar.bz2"

BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_FREESWITCH=y
# BR2_TARGET_ROOTFS_TAR is not set

I get:

Can you follow-up on this bug report by doing a pull request, as they
suggested?

Ditto.

(Note that I find it weird to fix a bug and add support for a new
architecture in the same patch. Two separate patches would have
definitely been better here.)

Not sure why there is a 05/99 here.

This should be MPLv1.1

Shouldn't this hook be rather handled by a patch ?

What do you mean by "patch configure.ac twice" ? Do you mean that there
are two patches touching it.

You should also explain in a comment why the normal
FREESWITCH_AUTORECONF = YES incantation doesn't work.

Other than that looks good. I would probably have applied if I didn't
encounter the build failure :-)

Thanks!
