Hotspot broken on linux-sparc, most likely after JDK-8199712 (Flight Recorder)

[John Paul Adrian Glaubitz]

Hello!

JDK-8199712 (Flight Recorder) most likely broke the build on linux-sparc
and it seems we're just missing a source file, either through a header
or a Makefile (see below).

I assume we need to build hotspot/cpu/sparc/vm_version_ext_sparc.cpp to
get this issue fixed.

I will look into this later unless someone is faster than me.
