Not a requirement for this port, given that this is GLIBC_PRIVATE so can 
always be changed later, but does sigaction actually need to live in 
libpthread?  Or given the work that's been done on moving functions from 
libpthread to libc (and the corresponding dynamic linker work that mean 
it's now possible to move versioned symbols like that), could the copy of 
sigaction in libpthread be removed?
