Return the size in bytes of the output file's headers. This is information which appears at the start
of the output file. You can use this number when setting the start address of the first section, if
you choose, to facilitate paging.
When producing an ELF output file, if the linker script uses the
tion, the linker must compute the number of program headers before it has determined all the
section addresses and sizes. If the linker later discovers that it needs additional program headers,
it will report an error

4.11. Implicit Linker Scripts

If you specify a linker input file which the linker can not recognize as an object file or an archive file,
it will try to read the file as a linker script. If the file can not be parsed as a linker script, the linker will
report an error.
An implicit linker script will not replace the default linker script.
