The IAR assembler doesn't accept '--preinclude', but it accepts -D.
This commit changes the way the config-related macros are propagated
to the IAR assembler to use '-D' instead of '--preinclude'. This is
the only change related to functionality, the others are small,
backward compatible changes to the config code to make passing arguments
to the toolchain instances easier.
Tested by compiled blinky with IAR, GCC_ARM and ARM for K64F.
For example .mbedignore in tools/ contains '*' and naturally should match all files, folders including tools/ itself. Without this fix, tools/ is added to the include path
This commit uses the previously introduced feature of generating
configuration data as a C header file rather than as command line macro
definitions. Each toolchain was modified to use prefix headers if
requested, and build_api.py was modified to set up the toolchain's
prefix header content using the data generated by the config system.
Tested by compiling blinky for GCC and ARMCC. I'm having a few issues
with my IAR license currently, but both ARMCC and IAR use the same
`--preinclude` option for prefix headers, so this shouldn't be an issue.
Note that at the moment all exporters still use the previous
configuration data mechanism (individual macro definitions as opposed to
a prefix header). Exporters will be updated in one or more PRs that will
follow.
