Ok, installed android-ndk-r18-beta2 with
build/tools/make_standalone_toolchain.py --arch=x86_64 --api 28 \
--stl=libc++ --install-dir=$(readlink -f ~/android/x86_64)
then
LDFLAGS=--static CROSS_COMPILE=~/android/x86_64/bin/llvm- \
make distclean defconfig
and
LDFLAGS=--static CROSS_COMPILE=~/android/x86_64/bin/llvm- make
Getconfig still died because
./generated/getconf.h:5:1: error: use of undeclared identifier '_CS_PATH'
_CS_PATH,_CS_V7_ENV

toys/posix/getconf.c:139:9: error: implicit declaration of function 'confstr' is

confstr(confstr_vals[j], toybuf, sizeof(toybuf));
Ok, switch that off and rebuild (I should add a compile-time probe for confstr),
and...

Your statement that this was in the NDK does not appear to be the case yet. Ok,
switch off CONFIG_LOG and:
lvm-strip: Unknown command line argument '-o'. Try:
'/home/landley/android/x86_64/bin/llvm-strip -help'
llvm-strip: Did you mean '-O'?
The prefixed llvm-strip doesn't know the "-o" option specifying output file.
Hmmm... well, it isn't in posix-2008, I suppose they have a point. I can cp and
then strip?

Oh bravo, stripping it made it 2k _bigger_. How the...

The host one knows how to strip it. And defconfig-ish build is still 930k. With
glibc it's:
$ ls -l toybox
-r-xr-xr-x 1 landley landley 1435128 Sep 5 14:59 toybox
And with musl-libc it's:
$ ls -l toybox
-r-xr-xr-x 1 landley landley 567240 Sep 5 15:02 toybox
So that's sane I suppose...
