    hppa: Fix bind_c_coms.f90 and bind_c_vars.f90 tests on hppa

    Commit 6271dd98 changed the default from -fcommon to -fno-common.
    This silently changed the alignment of uninitialized BSS data on
    hppa where the alignment of common data must be greater or equal
    to the alignment of the largest type that will fit in the block.
    For example, the alignment of `double d[2];' changed from 16 to 8
    on hppa64.

    The hppa architecture requires strict alignment and the linker
    warns about inconsistent alignment of variables.  This change broke
    the gfortran.dg/bind_c_coms.f90 and gfortran.dg/bind_c_vars.f90
    tests.  These tests check whether bind_c works between fortran
    and C.

    Adding the -fcommon option fixes the tests.  Probably, gcc and HP
    C are now by default inconsistent but that's water under the bridge.
