clang 3.8.0 amd64 targeting powerpc64 accepts -mlong-calls (instead of -mlongcall)

[Mark Millard]

Context: projects/clang380-import based amd64 FreeBSD used to try building for powerpc64

In csu/powerpc64/Makefile I replaced:

> CFLAGS+=        -I${.CURDIR}/../common \
>                 -I${.CURDIR}/../../libc/include \
>                 -mlongcall
. . .
> CC:=            gcc
> COMPILER_TYPE:= gcc

with

> CFLAGS+=        -I${.CURDIR}/../common \
>                 -I${.CURDIR}/../../libc/include \
>                 -mlong-calls
. . .
> #CC:=            gcc
> #COMPILER_TYPE:= gcc

and clang 3.8.0 targeting powerpc64 sailed through and past it without the slightest complaint about it. (It later reported that 'soft float is not supported for ppc64' from the -msoft-float that is always used for libstand.)
