Following the build process on https://wiki.dlang.org/Build_D_for_Android $ ldc-build-runtime --ninja --targetPreset=Android-aarch64 --buildDir=droid64 gives gc/os.d(254): Error: module `core.sys.posix.unistd` import `_SC_PHYS_PAGES` not found

@puneet created dlang/druntime pull request #2804 "Fix Issue 20222 -- druntime fails to build for Android" fixing this issue: - Fix Issue 20222 -- druntime fails to build for Android Commit https://github.com/dlang/druntime/commit/d931921a adds a dependency on _SC_PHYS_PAGES which is not defined in the module core.sys.posix.unistd for Android. This breaks compilation of druntime on/for Android platform. Porting this constant from Android bionic source file https://android.googlesource.com/platform/bionic/+/master/libc/include/bits/sysconf.h fixes the issue. https://github.com/dlang/druntime/pull/2804

Looks like there is already a fix on the stable branch. https://github.com/dlang/druntime/commit/e4a844e0
