Fixed armel/tizen support in build-commons.h (#32043)

This commit adds possibility to build .NET runtime
in Tizen's build environment (32-bit arm, little endian,
soft fp). Two issues was fixed:

1) wrong host os detection (tizen's build system is "armel",
   but not "arm");

2) build is allowed not only on "arm", "arm64" and "x64" hosts,
   but on "armel" host too.

Fixes #32042
