            Bug ID: 30875
           Summary: Output section type does not been applied to section
                    forced output by `. = .` assignment

Workaround patch, set flags by sectype at exp_init_os and
map_input_to_output_sections:case lang_assignment_statement_enum

Sometimes we may want to keep some empty section from discarding with ` . = .
`. But it seems that such empty section don't apply specific output section
type.

Example linker script:

SECTIONS
{
    foo (READONLY) :
    {
     *(bar)
     . = . ;
    }
}

Expected(when bar doesn't exist in input):
section foo with no SHF_WRITE flags.

Actually(when bar doesn't exist in input):
section foo with SHF_WRITE flag.

A workaround is also
