android: Require NDK 23 and use default linker lld
Using lld instead of hard-coding ld.gold speeds up
linking liblo-native-code.so from about 40 seconds
to about 10 seconds for my x86 debug Android build with
NDK 23.2.8568313.
lld was added in NDK 21, made default in NDK 22 [1].
lld doesn't know the `--no-keep-files-mapped` option,
so drop that as well.
ld.gold had previously been hard-coded in
commit c6dadf5035c8e1c31dbd3fccec167bd4a906bf54

android: Fix linking of liblo-native-code.so on aarch64.
, but lld wasn't available yet back then.
To make sure that lld is used by default, NDK >= 22
has to be used.
In addition, due to a clang bug in NDK 22.1.7171670 [2]
("Misspelled -fnostack-clash-protection"), building for
aarch64 Android with that NDK version would fail as follows:
clang++: error: unknown argument '-fno-stack-clash-protection'; did you mean '-fnostack-clash-protection'?
clang++ version:
$ /home/michael.weghorn/Android/Sdk/ndk/22.1.7171670//toolchains/llvm/prebuilt/linux-x86_64/bin/clang++ --version
Android (7155654, based on r399163b1) clang version 11.0.5 (https://android.googlesource.com/toolchain/llvm-project 87f1315dfbea7c137aa2e6d362dbb457e388158d)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /home/michael.weghorn/Android/Sdk/ndk/22.1.7171670//toolchains/llvm/prebuilt/linux-x86_64/bin
Rather than work around that bug on LO side, require
NDK 23.x right away, since that provides a clang where this is
fixed.
Both, non-debug as well as `--enable-dbgutil` builds
with NDK version 23.2.8568313 were successfully tested
for all 4 supported architectures and these devices:
* aarch64: Fairphone 3 Plus, LineageOS 19 (Android 12), API 31
* arm32: Samsung Galaxy S4 I9505, LineageOS 17.1 (Android 10), API 29
* x86:
* AVD: Nexus 4, API 16
* AVD: Pixel 2, API 30
* x86_64: AVD: Pixel 2, API 33
