scripts: add BUILD/HOST extra cflags/ldflags

Browse Source 
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).
