scripts: add BUILD/HOST extra cflags/ldflags

On some hosts, and for certain toolchains (eg. toolchain targetting
the upcoming Darwin), it may be necessary to pass arbitrary CFLAGS
and/or LDFLAGS when building the components.

And necessary infrastructure:
- EXTRA_{CFLAGS,LDFLAGS}_FOR_{BUILD,HOST} as config options
- pass those extra flags to components

Fix-up a slight typo in elf2flt at the same time (misnamed cflags).

    31       Add support for the Signal Processing Engine.  This will set up
    32       the toolchain so that it supports the SPE ABI extensions. This
    33       mainly targets Freescale e500 processors.
    34       
    35       Setting this option will append "spe" to the end of your target
    36       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
    37       configure/build system will know to include SPE ABI support. It
    38       will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS,
    39       and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you
    40       do not need to explicitly add them.
