@avoid dependency on NETBSDSRCDIR being set.

due to various things, non-build.sh builds don't have it set already
and it ends up defaulting to /usr/src, so if that doesn't exist or
is the wrong version, building libkern fails.

XXX: pullup-10, ..?

@PR port-arm/55897

Fix ABI mismatch for armhf runtime routines for floating-point arithmetics;
For hard-float arm variants, provide

(1) generic runtime routines with correct calling convention, and
(2) EABI runtime routines at the same time.

I've confirmed that no binary changes for kernels.

[PATCH] builtins: remove use of __attribute__((pcs("aapcs"))) on
  Windows
Windows does not honour the __attribute__((pcs)) on ARM.  Although this will
result in ABI mismatches, compiler-rt should largely be unneeded for resolving
dependencies as we generate MS ABI compliant library calls now for the most
part.

[Builtin] Unxfail tests for armhf
Summary:
Originally, a few tests fail for armhf target due to:
1) COMPILER_RT_ARMHF_TARGET was not set when building the lib
2) COMPILER_RT_ABI should not be defined as `__attribute__((pcs("aapcs")))` for armhf when building for both lib and tests
This addresshttps://bugs.llvm.org//show_bug.cgi?id=32261
mulsc3_test.c is a newly exposed issue, which will be addressed separately.

[PATCH] builtins: expand out the AEABI function stubs
These actually may change calling conventions.  We cannot simply provide
function aliases as the aliased function may have a different calling
convention.  Provide a forwarding function instead to permit the
compiler to synthesize the calling convention adjustment thunk.
Remove the `ARM_EABI_FNALIAS` macro as that is not safe to use.

[PATCH] [compiler-rt] Add back ARM EABI aliases where legal.
r303188 removed all the uses of aliases for EABI functions from
compiler-rt, because some of them had mismatched calling conventions.
Obviously, we can't use aliases for functions which don't have the same
calling convention, but that's only an issue for floating-point
functions with the hardfloat ABI.  In other cases, the stubs increase
size and reduce performance for no benefit.
This patch adds back the aliases, with appropriate checks to make sure
they're only used in cases where the calling convention matches.
llvm-svn: 314851
PR port-arm/55897
Fix ABI mismatch for armhf runtime routines for floating-point arithmetics;
For hard-float arm variants, provide
(1) generic runtime routines with correct calling convention, and
(2) EABI runtime routines at the same time.
I've confirmed that no binary changes for kernels.
