kconfig: fix compatibility with older flex versions

Older flex versions require there be no space between options and
their arguments. For example '-P zconf' is not correct and should
be '-Pzconf'. This is for example the case for flex-2.5.4 shipped
with CentOS 5.8.

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

     4
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."
