TyCoRep: Restore compatibility with 7.10.1

Sadly CallStack wasn't present in 7.10.1, breaking the build when
bootstrapping from this version.

This patch essentially disables CallStack support for stage1 builds with
7.10.*. This doesn't seem so unreasonable though as stage2 will still
work.

Test Plan: Validate with 7.10.1
