Allow building libutils etc. as shared libraries
When CFG_ULIBS_SHARED=y (default n), build libutils, libmpa/libmbedtls
and libutee as shared libraries (.so). The static archives (.a) are
still produced. The linker uses shared libraries by default when
present so TAs just need to be re-built to use the shared libraries.
For the time being, in-tree TAs are always linked statically for
practical reasons. Indeed, in-tree TAs (such as ta/avb) are likely
to be used as "early TAs". If such a TA was linked against shared
libraries, then those libraries would need to be installed in the
"early TA" area, too. While this works fine technically, it requires
some more steps in the Makefiles to make sure the proper dependencies
are installed and also it would mean that those libraries take
precedence over the ones potentially installed in the REE FS etc.
In other words, it would raise questions that we do not want nor need
to address now.

ta: link.mk: filter out dependency and command files from $(MAKEFILE_LIST)
Prevents ta.lds from being needlessly re-generated, such as in the
following test case:
$ make -s out/arm-plat-vexpress/ta/avb/ta.lds
$ make -s out/arm-plat-vexpress/core/kernel/console.o
$ make out/arm-plat-vexpress/ta/avb/ta.lds
CHK out/arm-plat-vexpress/conf.mk
CHK out/arm-plat-vexpress/include/generated/conf.h
CPP out/arm-plat-vexpress/ta/avb/ta.lds
The last line should not hapen because ta.lds exists already, and building
the unrelated console.o should not trigger a re-build.
The cause of the re-build is the dependency on $(MAKEFILE_LIST) which
contains *all* the files that record previous build command and
dependencies such as out/arm-plat-vexpress/core/kernel/.console.o.{d,cmd}.
Filter out those files, thus keeping only the static Makefiles (*.mk).
This is still more than needed since all the core *.mk are present, but
listing only the TA-related makefiles seems tricky (has to work both
inside and outside the OP-TEE build environment), and removing
$(MAKEFILE_LIST) altogether presents a risk that TA developers using the
TA dev kit will complain that their TA doesn't get re-built after a flag
is changed in a Makefile.

TA dev kit: shared library: add -f argument to ln
When creating a symbolic link <uuid>.elf -> libname.so, use the -f (force)
argument so that the command won't fail if the link already exists. It is
a very common case: the first time the library is built and the link is
created. Then whenever some source file is modified, the .so is re-linked
but the symbolic link is there already.

ta.ld.S: make .plt section of user TAs executable
This patch is preparatory work for the support of dynamically linked
user mode TAs.
The Procedure Linkage Table (.plt) section should be executable,
because it contains special code used to redirect function calls to
the proper destination in external (shared) libraries. Therefore, move
it into the executable segment.
A couple of blank lines are removed in the hope that it will make it
easier to see which sections are grouped together in the same segment.
