[dpdk-dev] [PATCH] mk: Quote $(KERNELCC) to allow ccache builds

[Simon Kagstrom <simon.kagstrom@netinsight.net>]

Otherwise building with KERNELCC="ccache gcc" will fail:

 == Build lib/librte_eal/linuxapp/igb_uio
 /usr/src/linux-headers-3.13.0-63-generic/arch/x86/Makefile:98: stack protector enabled but no compiler support
 /usr/src/linux-headers-3.13.0-63-generic/arch/x86/Makefile:113: CONFIG_X86_X32 enabled but no binutils support
 ccache: invalid option -- 'p'
 Usage:
     ccache [options]
     ccache compiler [compiler options]
     compiler [compiler options]          (via symbolic link)

 Options:
     -c, --cleanup         delete old files and recalculate size counters
                           (normally not needed as this is done automatically)
     -C, --clear           clear the cache completely
     -F, --max-files=N     set maximum number of files in cache to N (use 0 for
                           no limit)
     -M, --max-size=SIZE   set maximum size of cache to SIZE (use 0 for no
                           limit; available suffixes: G, M and K; default
                           suffix: G)
     -s, --show-stats      show statistics summary
     -z, --zero-stats      zero statistics counters

     -h, --help            print this help text
     -V, --version         print version and copyright information
