r264400:

  NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
  and finish the job. ncurses is now the only Makefile in the tree that
  uses it since it wasn't a simple mechanical change, and will be
  addressed in a future commit.

r265836:

  Remove last two NO_MAN= in the tree. In both of these cases, MAN= is
  what is needed.

Various bhyve fixes:
- Don't save host's return address in 'struct vmxctx'.
- Permit non-32-bit accesses to local APIC registers.
- Factor out common ioport handler code.
- Use calloc() in favor of malloc + memset.
- Change the vlapic timer frequency to be in the ballpark of contemporary
  hardware.
- Allow the guest to read the TSC via MSR 0x10.
- A VMCS is always inactive when it exits the vmx_run() loop.  Remove
  redundant code and the misleading comment that suggest otherwise.
- Ignore writes to microcode update MSR.  This MSR is accessed by RHEL7
  guest.
  Add KTR tracepoints to annotate wrmsr and rdmsr VM exits.
- Provide an alias for the userboot console and name it 'comconsole'.
- Use EV_ADD to create an mevent and EV_ENABLE to enable it.
- abort(3) the process in response to a VMEXIT_ABORT.
- Don't include the guest memory segments in the bhyve(8) process core dump.
- Make the vmx asm code dtrace-fbt-friendly.
- Allow vmx_getdesc() and vmx_setdesc() to be called for a vcpu that is in
  the VCPU_RUNNING state.
- Enable VMX in the IA32_FEATURE_CONTROL MSR if it not enabled and the MSR
  isn't locked.

Fix this build for clang.

MFC r259730:

To avoid having to explicitly test COMPILER_TYPE for setting
clang-specific or gcc-specific flags, introduce the following new
variables for use in Makefiles:

CFLAGS.clang
CFLAGS.gcc
CXXFLAGS.clang
CXXFLAGS.gcc

In bsd.sys.mk, these get appended to the regular CFLAGS or CXXFLAGS for
the right compiler.

MFC r259913:

For libstand and sys/boot, split off gcc-only flags into CFLAGS.gcc.

MFC r259927:

Fix pc98 build, by also forcing COMPILER_TYPE in sys/boot/pc98/boot2's
Makefile.

Use MK_SSP=no after including bsd.own.mk to disable SSP instead of user-knob

2013-09-29T20:20:17+00:00

WITH[OUT]_SSP to avoid hitting an error if user has WITH_SSP in their
make.conf. Ports now use this knob.

  make[7]: "/usr/src/share/mk/bsd.own.mk" line 466: WITH_SSP and
  WITHOUT_SSP can't both be set.

This is similar to previous cleanup done in r188895
