[RFC] Avoid spurious isolate-erroneous-paths failures

[Joseph S. Myers]

Removing attributes in glibc doesn't make sense when GCC has the same 
attributes built in.

GCC and glibc should be working together.  It's generally inappropriate to 
send a patch to one GNU project to work around a perceived deficiency in 
another GNU project without first raising the issue in the two projects 
together (i.e. in a thread CC:ed to both mailing lists) and coming to a 
common understanding between the two communities as to the right long-term 
fix.  (Workarounds for *old* versions of some other piece of software may 
be needed, of course.)
