[Qemu-devel] [PATCH 01/15] configure: add the disable-tcg option

[Yang Zhong <yang.zhong@intel.com>]

Add the disable-tcg option into configure and echo CONFIG_TCG=y into
$config_target_mak. The default tcg is enabled for all build. If tcg
is disabled in the build, only i386|x86_64 softmmu option can be disabled,
other softmmu of tagets and users build defaultly enabled the tcg. This
operation do not make big change with the older build command.

The new configure build command like below
(1)./configure
   tcg is defaultly enabled
(2)./configure --disable-tcg
   tcg is disabled in i386 and x86_64 softmmu build
   tcg is enabled in others softmmu and all users build
(3)./configure --disable-tcg --target-list=x86_64-softmmu, x86_64-linux-user
   tcg is disabled in x86_64 softmmu build
   tcg is enabled in x86_64 linux user build
