I've applied your patches, did a few tweaks, but I have some issues.
Could you restart from what I've done at:

  https://git.bootlin.com/users/thomas-petazzoni/buildroot/log/?h=pjsip-improvements

The improvements I've done are:

 - Tweak the commit titles

 - Use the --enable-<foo> options for the dependency-less codecs, since
   those options definitely exist.

 - Minor other formatting tweaks.

 - Select BR2_PACKAGE_ALSA_LIB_MIXER in the first patch, otherwise the
   build fails when this option is disabled.

Unfortunately, with all this, I see two problems. The first problem is
that the link command line contains flags like -Lyes/lib. This is due
to constructs such as:

                    LDFLAGS="$LDFLAGS -L$with_opencore_amr/lib"

So when you pass --with-opencore-amr, $with_opencore_amr has the value
"yes". You should change such options to
--with-opencore-amr=$(STAGING_DIR)/usr instead.

The second problem is that the following defconfig fails to build:

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-2017.11-rc1.tar.bz2"

BR2_PACKAGE_LIBPJSIP_CODEC_OPUS=y
BR2_PACKAGE_LIBPJSIP_CODEC_SPEEX=y

Could you have a look, fix those problems, and send an updated version ?

Thanks!
