bionic simply does not provide crti.o and crtn.o
https://github.com/aosp-riscv/platform_bionic/tree/master/libc/arch-common/bionic

I built the x86_64-linux-android toolchain and it succeeds. but fails for
aarch64.

That is the RISC-V Android port in progress.  It should not be used for
anything other than RISC-V, as RISC-V patches might have accidentally broken
other targets.  Use the official Android sources for Aarch64, or maybe
something distributed by Linaro.

i successfully built my own android linux toolchain on x86_64.
i think this is just a bug in libgcc since crti.o and crtn.o should not get
included.

This is my x86_64-linux-android toolchain. I does not need crti and crtn tbh.

build of arm-linux-androideabi-g++ is successful too. So it is aarch64 specific
issue for android in libgcc. I think Jakub can help me fix it.

Hi Jakub.
Any guideline on how to remove crti.o and crtn.o requirement in libgcc for
aarch64-linux-android? I would like to submit a patch to support android (for
x86_64, i686, armv7 and aarch64) on GCC, including the bug fix of libstdc++.

Why do you keep adding Jakub to CC?  He's not a mingw maintainer.

This is not mingw issue. it is libgcc's issue.

You get the same error on Linux hosted system too because gcc needs to find
crti.o and crtn.o for aarch64-linux-android targets, no matter what hosted
system you are. It has nothing to do with MinGW-w64 or Msys2 etc.

There is really no support for aarch64-linux-android included.  The target
headers for aarch64 don't include any support at all.
