[gold commit] PR gold/18048: Fix INCLUDE directive support for gold

[Cary Coutant <ccoutant at gmail dot com>]

This patch fixes INCLUDE directives in script files, so that when
an INCLUDE appears inside a sections block, section commands block,
or memory def block, the contents are parsed in the appropriate
context.
