- set GNUHOSTDIST
- move gthr-default.h to BUILDINCS, and add glue to add it to COPYHEADERS
- adjust COPYHEADERS to cope with files outside of dist/libstdc++-v3/.
# XXX these rules don't always work if the ${.TARGET} ends up being the
# copy in ../../arch/$arch/ and that version is older. (but will
# only break read-only source builds.)
Sorting out why isn't helped by the tests not reporting the erronous value.
Change the 'boilerplate' pattern used so that all the values are output.
Reduce the amount of faffy red tape as well.
Some of these reductions could be shared with other libm tests, but for
the moment they are defined in this file.
All these tests pass on my amd64 system, and when I run amd64 qemu.
Partial workaround for indefinite hangs when entropy is scarce or
buffered up. We need to do more to handle entropy that has been
buffered up -- see the comment for details -- but this will help for
now.

[*1] we should support this too!
[*2] we should look into this.
