Is there a way to set .bss section type to PROGBITS within a linker script ?

By definition, a .bss output section is NOBITS. You can't make a NOBITS
output section PROGBITS.

Well, technically you can make all input .bss sections be part of output
.data, and get the above effect:
...
SECTIONS {
...
.data
{
*(.data .data.* .gnu.linkonce.d.*)
*(.bss .bss.* .gnu.linkonce.b.*)
SORT(CONSTRUCTORS)
}
...
}
(Of course the side-effect will be that there's no output .bss anymore, so
if you really want to have the output .bss be SHT_PROGBITS, then H.J. is
right).
Ciao,
Michael.
