When creating core.elf with SBAT the grub-mkimage does not check if
an SBAT metadata file contains at least an SBAT header or not. It leads to
adding an empty SBAT ELF note for PowerPC and the .sbat section for EFI.
Fix this by checking the SBAT metadata file size against the SBAT header
size before adding SBAT contents to the ELF note or .sbat section.

On RISC-V, large code model is only compatible with position-depedent
code. However, the configure script checks availability of -mcmodel=large
before determining whether PIC/PIE is enabled, and disable them.
This is problematic with toolchains that enable PIE by default, where
check for -mcmodel=large will always fail with,
cc1: sorry, unimplemented: code model 'large' with '-fPIC'
and -mcmodel=medany will be silently used instead, causing relocation
failures at runtime with some memory layouts since -mcmodel=medany
requires all data and code to stay within a contiguous 4 GiB range.
Let's defer the check for -mcmodel=large until PIC/PIE is ensured disabled.

The original commit removes testing of GRUB's support for HFS+
wrapping and replaces it with testing that is an exact duplicate of
another test, namely HFS+ without wrapping. To start, the change is
misleading in that it suggests that the testing of HFS+ wrapping is
still taking place, when it is not. If it was desired to remove support
for testing the HFS+ wrapping, then the test should have been removed
entirely. Second, having a series of tests that are exactly the same is
just a waste of testing resources. And third, the justification for the
change is nonsensical. Just because a required program may not have
a required feature on a particular distro is not a reason that a test
should be removed. Reducing test coverage because some distros do not
have the tools GRUB needs to run certain tests goes against the testing
priority to have test coverage be as broad as possible. The fact is
that Debian, the officially supported distro for running the tests, does
have a mkfs.hfsplus that supports the -w parameter.

As explained in commit a21618c8a (tests: Test aborts due to missing
requirements should be marked as error instead of skipped) and in the
Automake manual[1], skipped tests are tests that should not be run, e.g.
running the ohci test on the powerpc-ieee1275 as there are no native ohci
drivers for that platform. Test that fail for reasons other than there is
a bug in GRUB code that is causing the test to fail are hard errors.
Commonly this is because the test is run in an improperly configured
environment, like required programs are missing. If a hard error condition
is identified with a SKIP return code, the person running the tests can not
know without investigating every skip if a SKIP in the tests was because
the test does not apply to the target being tested or because the user had
a misconfigured environment that was causing the test not to run. By
ensuring that a test is skipped only when it should not run, the person
running the test can be sure that there is no need to investigate why the
test was skipped.
This reverts commit bf13fed5f (tests: Skip tests if required tools are not available).
