From: Philippe Mathieu-Daudé <f4bug@amsat.org>

The previous attempt (commit f77147cd4de) doesn't work as
expected, as we still have CONFIG_TCG=1 when using:

  configure --disable-system --disable-user

Now than we have removed the use of CONFIG_TCG from target-dependent
files in tests/qtest/, we can remove the unconditional definition of
CONFIG_TCG in config_host.

This avoid to build a bunch of unrequired objects when building with
--disable-tcg (in particular the softfloat tests):

Before:

  $ make
  [1/812] Generating trace-qom.h with a custom command
  ...

After:

  $ make
  [1/349] Generating trace-qom.h with a custom command
  ...

A difference of 463 objects...
