How do I specify that object code should be placed in the small text area?

You can specify that object code should be placed in the small text area with -msmall-text. This will cause gcc to assume that the entire program (or library) fits in 4MB, and is thus reachable with a branch instruction. This reduces the number of instructions required for a function call from 4 to 1.

This flag should probably not be used in your global CFLAGS as some programs (or libraries) are larger than 4MB, and this will cause an ld error.

What do I do if any of these compiler flags cause a compile, linker, or runtime error?

As already mentioned, please use these CFLAGS cautiously. They may break your system. If you experience problems, try using less aggressive CFLAGS before filing a bug report.
