That would most likely not work for the Linux Kernel purpose that
surfaced this issue with bad .sframe in relocatable links.  To generate
stack traces using SFrame from Kernel modules they need to have a single
merged .sframe section.  Having multiple .sframe sections would require
pre-processing, something the merging would actually take care of.
