[IA64] fix compile failure with non modular builds 



Broke the non modular builds by moving an essential function into
modules.c.  Fix this by moving it out again and into asm/sections.h as
an inline.  To do this, the definitions of struct fdesc and struct
got_val have been lifted out of modules.c and put in asm/elf.h where
they belong.
