modpost: support objects with more than 64k sections
This patch makes modpost able to process object files with more than
64k sections. Needed for huge kernel builds (allyesconfig, for example)
with -ffunction-sections. 64k sections handling is covered, for example,
by this document:
"IA-64 gABI Proposal 74: Section Indexes"
