scripts: support extra host compiler flags

Allow the user to configure extra flags to pass to the host compiler
at build time. Applies to both C and C++.

Useful on Ubuntu to turn off the stack protector and fortify defaults
so the program stands a better chance of running on other distros.

reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,

MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,
yann@2173
     5
for e500v2 DPFP support) and will generate appropriate dual-precision

     6
floating point instructions by default.

Note: If building a Linux kernel with this toolchain, you will want to make

     9
sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions

    10
from getting into the kernel (which is currently unsupported). At this time,
yann@2173
    11
the kernel build system properly passes those two options, but older kernels
yann@2173
    12
were only passing -mno-spe by default."
