Description

When gcc is invoked with -ffunction-sections and/or -fdata-sections, it produces one section per symbol in output relocatable objects.
When producing a dynamic object, gld merges these sections into their logical main section. We should do the same thing.

This makes certain C++ applications (firefox) have vastly fewer sections, and link-edit orders of magnitude faster.
