[offloading] Error on missing symbols
When compiling an OpenMP or OpenACC program containing a reference in the
offloaded code to a symbol that has not been included in the offloaded code,
the offloading compiler may ICE in lto1.
Fix this by erroring out instead, mentioning the problematic symbol:
...
error: variable 'var' has been referenced in offloaded code but hasn't
been marked to be included in the offloaded code
lto1: fatal error: errors during merging of translation units
compilation terminated.
...
