objtool: Validate disassembler headers in libopcodes probegrafted

commit 3f2de814c059 ("objtool: Fix libopcodes linking with static libraries")
tested for libopcodes availability by linking a test snippet with a forward
declaration of disassemble_init_for_target().

However, testing symbol linkage with an extern declaration only verifies
the presence of the library (.so/.a) and bypasses checking for development
headers (binutils-dev). On systems where libopcodes is present without
development headers installed, the probe succeeds, enabling BUILD_DISAS.
Subsequent compilation of objtool then fails:

  fatal error: 'bfd.h' file not found
    113 | #include <bfd.h>

Additionally, the probe invokes $(HOSTCC) without $(HOSTCFLAGS), ignoring
any sysroot or include flags specified for the host compiler.

Fix this by including <bfd.h> and <dis-asm.h> directly in the test snippet,
passing $(HOSTCFLAGS) so host compiler options are respected, and defining
PACKAGE="objtool" to satisfy the configuration check in <bfd.h>.

+Linux kernel project continuity
+===============================
+
+The Linux kernel development project is widely distributed, with over
+100 maintainers each working to keep changes moving through their own
+repositories. The final step, though, is a centralized one where changes
+are pulled into the mainline repository. That is normally done by Linus
+Torvalds but, as was demonstrated by the 4.19 release in 2018, there are
+others who can do that work when the need arises.
+
+Should the maintainers of that repository become unwilling or unable to
+do that work going forward (including facilitating a transition), the
+project will need to find one or more replacements without delay. The
+process by which that will be done is listed below. $ORGANIZER is the
+last Maintainer Summit organizer or the current Linux Foundation (LF)
+Technical Advisory Board (TAB) Chair as a backup.
+
+- Within 72 hours, $ORGANIZER will open a discussion with the invitees
+  of the most recently concluded Maintainers Summit. A meeting of those
+  invitees and the TAB, either online or in-person, will be set as soon
+  as possible in a way that maximizes the number of people who can
+  participate.
+
+- If there has been no Maintainers Summit in the last 15 months, the set of
+  invitees for this meeting will be determined by the TAB.
+
+- The invitees to this meeting may bring in other maintainers as needed.
+
+- This meeting, chaired by $ORGANIZER, will consider options for the
+  ongoing management of the top-level kernel repository consistent with
+  the expectation that it maximizes the long term health of the project
+  and its community.
+
+- Within two weeks, a representative of this group will communicate to the
+  broader community, using the ksummit@lists.linux.dev mailing list, what
+  the next steps will be.
+
+The Linux Foundation, as guided by the TAB, will take the steps
+necessary to support and implement this plan.
