[IA64] fix compile failure with non modular builds

Browse Source 
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.
