Build static host binaries.

If you wish to move the toolchain to another host, and you are not
|
|
confident that this host has the required versions of system libs, then
|
|
you can say 'Y' here, and all the host tools will be linked statically.
|

The impacted tools are:
|
|
- the cross-binutils (GNU binutils, elf2flt)
|
|
- the cross-compiler (gcc)
|
|
- the cross-debugger (gdb)
|
|
|

The default is 'N', to build dynamicaly-linked host binaries.

NOTE: this has no connection to whether the target libraries will be
|
|
dynamic or static. This only applies to the tools themselves.
