[gold][patch] PR 10842: fix for gold crash with LTO and --gc-sections

[Cary Coutant <ccoutant at google dot com>]

This patch fixes a gold crash when compiling in LTO with
--gc-sections. If the compiler inlines all occurrences of a function
and removes that function from the generated objects, gold crashes
with a SIGSEGV. The problem was that when the symbol was first added
as an absolute symbol (SHN_ABS), the "is_ordinary" flag was set,
causing gold to later attempt to use SHN_ABS as an actual index into
the section table.

OK?
