c114ca5247 Reapply "build: fix rule for building dynamic files"
This reverts commit 7eab365219 and fixes
the pattern rule requirement "% must match a non-empty stem" to match at
least '.' in the pattern.

This whole file could actually be substantially simplified to just:

	%.$(SUFFIX): %.c
		$(CC) $(CFLAGS) -c $< -o $(@F)

	%.$(PSUFFIX): %.c
		$(CC) $(PFLAGS) -c $< -o $(@F)

if desired to entirely avoid the copy-paste duplication, but the net
effect is the same.

This adds all the relevant bits and pieces to add a `shgemv` path as
well as a future `hgemm`/`hgemv` path in a similar model to `sb` and `b`
interfaces.

I've also fixed a few bits and pieces around `shgemm` which didn't build
in a few situations.

7fcad02dc2 fix RVV 1.0 detection code
There were a couple of issues with the detection code used to check
for RVV 1.0 on kernels that do not support hwprobe.

1. The vtype clobber was missing
2. The wrong form of vsetvli was being used. The vsetvli x0, x0 form
   is inappropriate for this use case as it can only be safely used
   in code where the value of vtype is known.  The use of vsetvli
   x0, x0 here can lead to a failure to detect RVV 1.0, if,
   for example, the vill bit happens to be set before
   detect_riscv64_rvv100 is called.

We fix both issues by adding the missing clobber and replacing the
first parameter to vsetvli with t0 (which we add to our clobbers).

ce79fe12fd disable fp16 flags on RISC-V unless BUILD_HFLOAT16=1
The compiler options that enable 16 bit floating point instructions
should not be enabled by default when building the RISCV64_ZVL128B
and RISCV64_ZVL256B targets.  The zfh and zvfh extensions are not part
of the 'V' extension and are not required by any of the RVA profiles.
There's no guarantee that kernels built with zfh and zvfh will work
correctly on fully compliant RVA23U64 devices.

To fix the issue we only build the RISCV64_ZVL128B and RISCV64_ZVL256B
kernels with the half float flags if BUILD_HFLOAT16=1.  We also update
the RISC-V dynamic detection code to disable the RISCV64_ZVL128B and
RISCV64_ZVL256B kernels at runtime if we've built with DYNAMIC_ARCH=1
and BUILD_HFLOAT16=1 and are running on a device that does not support
both Zfh and Zvfh.
