Hi,

I am trying to build Ruby 2.1 for F21 and I observe following test
errors:

   3) Error:
TestProcess#test_clock_getres_constants:
Errno::E524: Unknown error 524 - clock_getres
     /builddir/build/BUILD/ruby-2.1.0-preview1/test/ruby/test_process.rb:1752:in
`clock_getres' /builddir/build/BUILD/ruby-2.1.0-preview1/test/ruby/test_process.rb:1752:in
`block in
test_clock_getres_constants' /builddir/build/BUILD/ruby-2.1.0-preview1/test/ruby/test_process.rb:1749:in
`each' /builddir/build/BUILD/ruby-2.1.0-preview1/test/ruby/test_process.rb:1749:in
`test_clock_getres_constants'
   4) Error:
TestProcess#test_clock_gettime_constants:
Errno::E524: Unknown error 524 - clock_gettime
     /builddir/build/BUILD/ruby-2.1.0-preview1/test/ruby/test_process.rb:1676:in
`clock_gettime' /builddir/build/BUILD/ruby-2.1.0-preview1/test/ruby/test_process.rb:1676:in
`block in
test_clock_gettime_constants' /builddir/build/BUILD/ruby-2.1.0-preview1/test/ruby/test_process.rb:1673:in
`each' /builddir/build/BUILD/ruby-2.1.0-preview1/test/ruby/test_process.rb:1673:in
`test_clock_gettime_constants'


It looks like CLOCK_REALTIME_ALARM and CLOCK_BOOTTIME_ALARM are not
supported, but the error code is completely strange to me. According to
the documentation, it should return EINVAL.

http://pubs.opengroup.org/onlinepubs/9699919799/functions/clock_getres.html
  |
  | [EINVAL]
  | The clock_id argument does not specify a known clock.

Any help is appreciated.

Thanks
