[PATCH 8/8] gdb: Add extra early initialization symbols for i386-pc

From: Glenn Washburn
Subject: [PATCH 8/8] gdb: Add extra early initialization symbols for i386-pc
Date: Mon, 27 Feb 2023 15:15:38 -0600

Add symbols for boot.image, disk.image, and lzma_decompress.image if the
target is i386-pc. This is only done for i386-pc because that is the only
target that uses the images. By loading the symbols for these images,
these images can be more easily debugged by allowing the setting of break-
points in that code and to see easily get the value of data symbols.
