[Bug translator/10280] New: allow relaxing of `uname -r` matching runtime assertion

- Reply-to: sourceware-bugzilla at sourceware dot org
On ABI-compatible kernel series such as RHEL5, a module compiled against
an older kernel can sometimes be loaded correctly on later kernels of the
same series. Systemtap prohibits this by checks in translate.cxx
(c_unparser:;emit_module_init) that matches UTS_RELEASE against the
compile-time `uname -r`. This check is valuable in some contexts, but
seems counterproductive here. So let's give users an option to remove
this check.
(Perhaps it could be heuristically automated if no highly release/build-specific
data such as debuginfo is used in a given script.)
