Compile libgcov without stack protection. It can be linked into both static and dynamic binaries compiled with or without stack protection and should not depend on libssp_nonshared.a symbols. Discussed with: kib PR: bin/139052

Convert gnu to using SRCTOP Prefer SRCTOP over CURDIR/../../contrib, etc. However, retain the "up one level" instances of ../ because they are really relative to this part of the tree and not a means to find the root of the tree. As such, it's better to leave them since that further the goal of being able to move directories if watned to in the future.

Follow-up r297842: Rework header generation to fix always rebuilding. This reworks the handling of common headers to just include the needed logic rather than invoke MAKE.

Update bmake glue to build GCC 4.2. Also: Switch FreeBSD to use libgcc_s.so.1. Use dl_iterate_phdr to locate shared objects' exception frame info instead of depending on older register_frame_info machinery. This allows us to avoid depending on libgcc_s.so.1 in binaries that do not use exception handling directly. As an additional benefit it breaks circular libc <=> libgcc_s.so.1 dependency too. Build newly added libgomp.so.1 library, the runtime support bits for OpenMP. Build LGPLed libssp library. Our libc provides our own BSD-licensed SSP callbacks implementation, so this library is only built to benefit applications that have hadcoded knowledge of libssp.so and libssp_nonshared.a. When linked in from command line, these libraries override libc implementation.

Add compiler support for the ARM EABI. ARM EABI support is disabled by default and can be enabled by setting WITH_ARM_EABI when building, however only the kernel-toolchain target will work with this flag until the rest of the support is added.

Remove MK_ARM_EABI, the armeb issues have been fixed. The code to support the oabi is still in the tree, but it is expected this will be removed as developers work on surrounding code. With this commit the ARM EABI is the only supported supported ABI by FreeBSD on ARMa 32-bit processors. X-MFC after: never Relnotes: yes Differential Revision: https://reviews.freebsd.org/D876

When MAKEOBJDIRPREFIX points to a case-insensitive file system, the build can break when different source files create the same target files (case-insensitivity speaking). This is the case for object files compiled with -fpic and shared libraries. The former uses an extension of ".So", and the latter an extension ".so". Rename shared object files from *.So to *.pico to match what NetBSD does. See also r305855 MFC after: 1 month Sponsored by: Bracket Computing Differential Revision: https://reviews.freebsd.org/D7906
