Problem with gold linker and 7.8.1rc2

[harry]

If I use the gold linker with 7.8.1rc2 (RHEL bindist), anything using network
in build-depends - even if it's not used in the code - fails to build with:

libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to
'sem_unlink'
libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to
'sem_open'
libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to
'sem_wait'
libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to
'sem_getvalue'
libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to
'sem_close'
libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to
'sem_post'
libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to
'sem_trywait'

(I only have shared libraries on this machine.)
