Add a Makefile for building the cloudabi32 kernel module. Where the cloudabi64 kernel can be used to execute 64-bit CloudABI binaries, this one should be used for 32-bit binaries. Right now it works on i386 and amd64.

sys/modules: normalize .CURDIR-relative paths to SRCTOP This simplifies make output/logic Tested with: `cd sys/modules; make ALL_MODULES=` on amd64 MFC after: 1 month Sponsored by: Dell EMC Isilon

Properly use MACHINE_CPUARCH for finding cloudabi*_sysvec.c. The build of the cloudabi32 kernel module currently fails for PC98. In the case of PC98, we just want to use the code for i386. Reported by: np

.PATH: ${SYSDIR}/${MACHINE_CPUARCH}/cloudabi32
Use both the MACHINE and MACHINE_CPUARCH directories for finding sources. When fixing this module to build on PC98, I actually broke the build on ARM64. On PC98 we need to pull in the sources from the MACHINE_CPUARCH (i386), but on ARM64 we need to use the MACHINE, as MACHINE_CPUARCH is set to aarch64 instead of just arm64.

Pick the right vDSO file/linker flags when building cloudabi32.ko on ARM64. The recently imported cloudabi_vdso_armv6_on_64bit.S should be the vDSO for 32-bit processes when being run on FreeBSD/arm64. This vDSO ensures that all system call arguments are padded to 64 bits, so that they can be used by the kernel to call into most of the native implementations directly.

Support armv7 builds for userland Make armv7 as a new MACHINE_ARCH. Copy all the places we do armv6 and add armv7 as basically an alias. clang appears to generate code for armv7 by default. armv7 hard float isn't supported by the the in-tree gcc, so it hasn't been updated to have a new default. Support armv7 as a new valid MACHINE_ARCH (and by extension TARGET_ARCH). Add armv7 to the universe build. Differential Revision: https://reviews.freebsd.org/D12010

Make the cloudabi32 kernel module available on ARMv6. Now that all of the necessary bits for ARMv6 support for CloudABI have been checked in, let's hook the kernel module up to the build and document its existence.
