crosstool-ng/patches/gdb/6.3/750-debian_sparc-singlestep.patch
Yann E. MORIN" 8d3f0a8781 Debug facilities:
- add a framework to easily add new ones
  - add gdb as a first debug facility
  - add patches for gdb
After the kernel checked its installed headers, clean up the mess of .checked.* files.
Reorder scripts/crosstool.sh:
  - dump the configuration early
  - renice early
  - get info about build system early, when setting up the environment
  - when in cross or native, the host tools are those of the build system, and only in this case
  - elapsed time calculations moved to scripts/functions
Remove handling of the color: it's gone once and for all.
Update tools/addToolVersion.sh:
  - handle debug facilities
  - commonalise some code
  - remove dead tools (cygwin, tcc)
Point to my address for bug reports.
