    [PR105224] C++ modules and AAPCS/ARM EABI clash on inline key methods
    
    g++.dg/modules/virt-2_a.C fails on arm-eabi and many other arm targets
    that use the AAPCS variant.  ARM is the only target that overrides
    TARGET_CXX_KEY_METHOD_MAY_BE_INLINE.  It's not clear to me which way
    the clash between AAPCS and C++ Modules design should be resolved, but
    currently it favors AAPCS and thus the test fails, so skip it on
    arm_eabi.
