How can I build bionic alone for development purpose？

[Chen Wang]

hello，
I am making some changes in bionic and want to know if any method to only build the bionic libs. 

I get source code of bionic by git clone https://android.googlesource.com/platform/bionic, but I find the build of this repo depends on aosp build framework. Before actual build of libc/libdl, soong will scan and load all bp files under AOSP to construct the ninja file, it cost too much time.

I wonder if there is a simple and convenient method to build bionic only in direct method, for example, how to disable scanning of other sub-modules which bionic has no dependency on?

Thanks, in adv.
