I''m having the same problem .cross compiling from slackware 32bit to 64. I used
the  clfs book but had to change for the extra languages. java compiles at iirc
chapter 5 funal gcc(to cross-tools) then 6.4 iirc compiling to /tools. then I
did what was needed for the reboot. compiled glibc with the --prefix=/usr 32bit
build and then the 64bit build. It over writes the syscall.h of course. The
32bit one has both SYS_sigaction and SYS_rt_sigaction bit the 64bit only has the
SYS_rt_sigaction line . I notice in glibcheaders for FC etc rpms it has the same
syscall.h with no SYS_sigaction in it so how did FC over come this O.o thanks 
(slackware I did recompile to gcc 4.1.1 before I started the cross compile
,needed for ada as 3.4.6 was too old) gcc 4.1.1,glibc 2.4
