sets PICFLAGS=-fPIC and we pick this via CSHLIBFLAGS to build .o objects.
This breaks the sun2 port, because with -fPIC we end up producing short
relative pic branches for $_exception_handler, so we get relocation errors.
Arguably:
1. MKPIC=no should not set PICFLAGS in bsd.lib.mk
2. CSHLIBFLAGS should not be used in non pic (.o) productions

them so we get DT_TEXTREL problems.

Remove all (most?) of the softfloat functions as they clash with the
libc versions. Also stop using t-bpapi as it adds stuff that's also in
libc. Bring in the parts of t-bpapi that we do want.

mode), if no lwp is signaled, just stay with the current (inferior_ptid.lwp).
This fixes gdb -p to a threaded process with all threads active.
Previously we eroneously restored an lwp of 0 (returned as sentinel from
ptrace) to inferior_ptid.lwp, which then would not match any thread in
thread_list and caused assertion failures.
Extentions (clang already defines them):
__ARM_PCS is defined to 1 if the default procedure calling standard for
the translation unit conforms to the "base PCS" defined in [AAPCS].
__ARM_PCS_VFP is defined to 1 if the default is to pass floating-point
parameters in hardware floating-point registers using the "VFP variant PCS"
defined in [AAPCS].
gcc: avoid generating negative values to DW_AT_byte_size.
There is a bug in gcc (GCC/35998) where dwarf reports
sizes of unsigned -1 (0xffffffff).
On NetBSD this generated a faulty CTF entry which then
caused a segfault in ctfmerge. The issue was worked
around in NetBSD's Dtrace but since the issue originated
in gcc, it seems reasonable to fix it here.
Thanks to Christoph Mallon for pointing out a correct fix.
it and the OS has enabled XGETBV for application use.
It might need to also check XCR0[2] (having executed XGETBV) to check that
the kernel actually supports saving the YMM registers, but I suspect the
kernel might defer setting that until the first fault.

the TOOLDIR version of libnbcompat, associated include files,
and associated defs.mk file, instead of the version from the
.OBJDIR of src/tools/compat. This should fix PR 47188.
GCC/i386 has code to lower the required alignment for long long to 32bit
as the CPU doesn't need more. It is also using the same mode for setting
up the MMX registers and in turn, the stack slots reserved for spilling
require 32bit alignment. The actual vector types used keep the original
64bit alignment, so when the compiler wants to spill a MMX register, it
hits an assertion. Fix this by using the vector type as raw type for MMX
registers.
