Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de> to reorganize
the build-tools layout to simplify it. This script reorganizes and simpilfies the build-tools subdirectories. It moves all source-files and scripts to c/build-tools/. This will enable use to use this directory directly to refer to the build-tools instead of copying them around in a "preinstall" step in future. However, RTEMS's autoconf Makefile.ins and *.cfg files are not yet prepared to apply this approach and therefore require additional work.

- * unhex
- * convert a hex file to binary equivalent. If more than one file name

- * Supported input formats are Intel hex, Motorola S records, and TI 'B'
- * records.
- *
- * Intel hex input format is
- * Byte
- * 1 Colon :
- * 2..3 Record length, eg: "20"
- * 4..7 load address nibbles
- * 8..9 record type: "00" (data) or "02" base addr
- * 10..x data bytes in ascii-hex
- * x+1..x+2 cksum (2's compl of (len+addr+data))
- * x+3 \n -- newline
