When a string variable already had a source-level default value, the -ldflags "-X" flag was silently ignored and the variable remained the default value at runtime. Fix by stripping the InitOrder entry for each -X variable before LoadSSA() is called. With no entry in InitOrder, go/ssa emits no init store, so the global stays zero-valued in the IR. makeGlobalsModule still injects the actual -X values at final link time. The -X values remain out of the per-package build cache with only the variable names appearing in the cache key. Signed-off-by: deadprogram <ron@hybridgroup.com>
