Minimal configuration script for msp430-libc to update the features
header msp430libc.h and the Makefile.
This script must be run from the root directory of the source area.
There is no support for separated builds at this time.
--disable-printf-int64 : Remove 64-bit integer support to printf formats
--disable-printf-int32 : Remove 32-bit integer support from printf formats
--enable-ieee754-errors : Use IEEE 754 error checking in libfp functions
--prefix=/path/for/install : Where to install (now ${MSP430LIBC_PREFIX})
Use --disable-foo to counter --enable-foo.
