FAIL: gfortran.dg/bind_c_coms.f90   -O0  (test for excess errors)
Excess errors:
ld: (Warning) Symbol "com" in "/var/tmp//cc14WyWs.o" does not satisfy the
required 16-byte alignment in "/var/tmp//cc4g1Pgg.o".
1 warnings.

Fails at all optimizations.

We now have in bind_c_coms_driver.s:

        .section        .bss
        .align 8
        .type   com, @object
        .size   com, 16
        .align 8
com:
        .block 16

We used to have:

        .section        .bss
com     .comm 16

The later provides 16-byte alignment.

Looks to me like there are problems with both pa_asm_output_aligned_bss() and
pa_asm_output_aligned_common().  It looks like allocations in the BSS need to
be aligned to a power of 2 alignment greater than the size of the block.
