crosscompile macosx to android fails

[yichoi]

It looks like log2f symbol is missing

Do you have a full gist available? I wonder if we're trying to upload *.dylib to the emulator when we should be uploading *.so...

[yichoi]

android does not need *.dylib. just *.so are required. please find the script mk/test.mk what I wrote before.
I can provide full gist however repeated messages are almost same

[yichoi]

rust_android_dummy.c is compiled for android properly.
librust_builtin.a has log2f properly.
librustrt-xxx.so does not have log2f
libstd-xxx.so has log2f
