    pdp11: Fix handling of common (local and global) vars [PR94134]

    As mentioned in the PR, the generic code decides to put the a variable into
    lcomm_section, which is a NOSWITCH section and thus the generic code
doesn't
    switch into a particular section before using
    ASM_OUTPUT{_ALIGNED{,_DECL}_}_LOCAL, on many targets that results just in
    .lcomm (or for non-local .comm) directives which don't need a switch to
some
    section, other targets put switch_to_section (bss_section) at the start of
    that macro.
    pdp11 doesn't do that (and doesn't have bss_section), and so emits the
    lcomm/comm variables in whatever section is current (it has only
.text/.data
    and for DEC assembler rodata).

    The following patch fixes that by putting it always into data section, and
    additionally avoids emitting an empty line in the assembly for the lcomm
    vars.
