build: use CFLAGS32/CFLAGS64 when building in-tree TAs

[jforissier]

Commit 19fdfcf ("build: ldelf and TAs can rely on CFLAGS32/CFLAGS64")
only partially implements what is mentioned in the commit description.
The ldelf part is OK, but in-tree TAs still don't use CFLAGS32 or
CFLAGS64. The reason is that the submodule name $(sm) is not ta_arm32 or
ta_arm64 like for TAs build with the "dev kit". Instead, $(sm) is the
name of the directory (such as "avb" for core/ta/avb, "pkcs11" for
core/ta/pkcs11, etc.). Therefore, it is not arch-bits-ta_arm32 or
arch-bits-ta_arm64 that needs to be set but arch-bits-$(sm).

I am restarting IBART which reported an error that doesn't seem related to this change (random timeout?)

Indeed that does the trick, thanks!
