Missing mbed_config.h from exported project

[vargham]

Description

• Type: Bug
• Priority: Major

There is no mbed_config.h in exported project. Tried with STM32F103, STM32F429, LPC1768 mbed and mbed-os lib also. Tried with EmBlocks, GCC make and SW4STM32. Seems all targets and IDEs are affected.

$ make
Compile: main.cpp
cc1plus.exe: fatal error: mbed_config.h: No such file or directory
compilation terminated.
make[1]: *** [/cygdrive/d/_dev/_tmp/arm_tests/mbed_blinky/Makefile:241: main.o] Error 1
make: *** [Makefile:26: all] Error 2

Bug

Target
STM32F103|STM32F429|LPC1768|Maybe others

Toolchain:
Online exporter

Toolchain version:
Current online exporter (2017-03-30)

Expected behavior
Exported project should contain all files.

Actual behavior
Build fails, missing mbed_config.h

Steps to reproduce
Create project "mbed_blinky" for LPC1768 and export it to offline GCC makefile. Build will fail because missing mbed_config.h

I've just hit something related, that I had to use old project.py script to test something for mbed 2 and this is traceback:

KeyError: 'mbed_config.h'

(missing mbed_config ?)

Workaround: Copy mbed_config.h from previous export. (This bug was not present before last week.)

@0xc0170 that's the error that #4013 Fixes. @vargham I'll look into the online problem.
