Hi,

I got a error while building master branch on FreeBSD.
Here is a log.

$ gmake T=x86_64-native-bsdapp-clang config
cc: error: unknown argument: '-fdirectives-only'
cp: /usr/home/mukawa/work/dpdk/build/.config_tmp: No such file or directory
cp: /usr/home/mukawa/work/dpdk/build/.config_tmp: No such file or directory
gmake[3]: Nothing to be done for 'depdirs'.
Configuration done


Here is log came from 'uname'

$ uname -a
FreeBSD eris.hq.igel.co.jp 10.1-RELEASE FreeBSD 10.1-RELEASE #0 r274401:

I've tried to remove '-fdirectives-only' from mk/rte.sdkconfig.mk like
below.
With the fixing,  It seems I can compile and run testpmd.
(Obviously, we should not merge below patch, but I've done just for testing)

diff --git a/mk/rte.sdkconfig.mk b/mk/rte.sdkconfig.mk

$(RTE_OUTPUT)/.config; then \
                        cp $(RTE_OUTPUT)/.config_tmp
$(RTE_OUTPUT)/.config ; \


Also, I've checked /usr/ports/net/dpdk, and found below line.
(It seems above ports dpdk package is based on DPDK-1.8.)


                $(CPP) -undef -P -x assembler-with-cpp \
                 -ffreestanding \
               -o $(RTE_OUTPUT)/.config_tmp $(RTE_CONFIG_TEMPLATE) ; \

So, I guess we should not add '-fdirectives-only' for flags of $(CPP)
for BSD system like dpdk package of ports.

Thanks,
Tetsuya
