glibc-2.9 was the last time i tried s390/s390x, and it didnt whine about long 
double issues.  when exactly did you hit troubles ?  during header install and 
thus no C compiler was yet available ?  under Gentoo, a bunch of cache vars 
are forced just for the headers step as there is no compiler to test.  those 
include mlong double tests.
	libc_cv_mlong_double_128=yes
	libc_cv_mlong_double_128ibm=yes

i dont believe ive used crosstool-ng before.  Gentoo has a cross-compiler 
generation tool integrated with its build scripts called crossdev.

that would be good
