Druntime could easily implement it's own qsort. https://github.com/ldc-developers/ldc/issues/490#issuecomment-28356710

An existing (though copyrighted) implementation was removed with https://github.com/D-Programming-Language/druntime/commit/45f1755cf13a1a376cc1572b5a9327d95fc0db75. Also the used qsort_r isn't present in older glibc versions (see bug 10508).

There is a qsort in bionic, looks like it comes from FreeBSD: https://github.com/android/platform_bionic/blob/master/libc/include/stdlib.h#L91 https://github.com/android/platform_bionic/blob/master/libc/upstream-freebsd/lib/libc/stdlib/qsort.c#L110 There is no qsort_r, which is what Druntime uses on linux by default: my guess is that's what Elvis tried to use. But you can use the fallback block from rt/qsort.d that calls qsort on Android and I believe it should work fine.
