 As there was no problem in the past (at least back to netbsd-6 through
 8.99.26), there must have been something that served that purpose.
 
 The claimed missing symbol is perhaps a GCC internal implementation
 substituted for missing hardware functionality?  In case it's relevant,
 the GCC in use for 8.99.26 appears to have been GCC-6.
