Large generated binary file

[yilun-zhangs]

Thanks for your great work, it is very helpful to do cross building.

With the help of hermetic_cc_toolchain I can generate ARM aarch64 binary file.
But I found the size of the binary file is much larger than x86-64 version, they use same code.

e.g. x86-64 version is about 6.6M, but ARM aarch64 is about 47M.
Do you know is there compile option that could reduce the size of generated ARM aarch64 binary file?
