[ptxdist] [PATCH] host-tf-a: fix build with v2.14

[Roland Hieber]

TF-A >= v2.14 now tries to detect an ARM toolchain early in the Makefile
and errors out if it cannot find one before even evaluating the
'fiptool' recipe. Even though we only use the host toolchain to build
fiptool, set the same build environment as for the tf-a recipe to make
it work again. HOST_TF_A is usually only selected by images, not by TF_A
directly, so make sure that we can use TF_A_* variables with an
additional 'select' in the platformconfig menu.

(This problem only happens on build hosts without an aarch64-linux-gnu-*
toolchain installed in /usr/bin/, to which TF-A defaults when no ARCH is
set. However PTXdist includes the selected_toolchain in PATH when
building host-tf-a, so a matching cross toolchain can always be found.)

Hm. Additional investigation showed that AARCH32_SP=sp_min was also needed here
to make it work on the build server. However I don't understand yet why a simple
'make fiptool' in a fresh TF-A Git checkout does the correct thing, and why it
doesn't work on the build server.
