- Split INFO strings in source into multiple pieces
to make sure assembly or other listings produced
by the compiler are never matched by the regex
- Store INFO strings via pointer instead of array
to convince some compilers to store the string
literally in the binary
- This should help make it work for sdcc 2.8.0 RC1
- Write a single source file into the compiler id directory
- This avoid requiring the compiler to behave correctly with
respect to include rules and the current working directory
- Helps to identify cross-compiling toolchains with unusual
default behavior
