crtbegin_dynamic and crtbegin_static are essentially identical,
minus a few trivial differences (comments and whitespace).
Eliminate duplicates.

-# - the address of the raw data block setup by the Linux

-# - address of an "onexit" function, not used on any

-# - address of the "main" function of the program. We
