George Rimar 1022112d77 [ELF] - Linkerscript: make section with no content to be SHT_PROGBITS by default.
Imagine next script:

SECTIONS { BYTE(0x11); }

Section content written to disk will be 0x11. Previous LLD behavior was to make this
section SHT_NOBITS. What is not correct because section has content.
ld.bfd makes such sections SHT_PROGBITS, this patch do the same.

This fixes PR32537

Rafael Espindola 5fcc99c27d Also skip regular symbol assignment at the start of a script.
Unfortunatelly some scripts look like

kernphys = ...
. = ....

and the expectation in that every orphan section is after the
assignment.

Rafael Espindola 7fe4ec9b3a Don't put an orphan before the first . assignment.
This is an horrible special case, but seems to match bfd's behaviour
and is important for avoiding placing an orphan section before the
expected start of the file.
