Excellent.

I'm fully aware that the change to enable isn't upstream.  I'm still 
debating in my mind whether
this should be done or not.  At the moment, there are no additional 
changes to the compiler-rt
code as far as I know. However, things seem fragile and possibly this 
library is unsuitable for
an architecture that is only supported by Gentoo and Debian unstable 
Linux ports.

I'm not sure what the issue is with the hppa kernel typedef for time_t.  
It seems defined by the
generic linux type definitions.  If this needs to be changed for 
libsanitizer, I would like to
understand why.  As far as I can tell, hppa isn't unique in using time_t 
in uapi/asm/stat.h
although the majority of ports only use base types.
