Dash shipped with Ubutu-11.10 as /bin/sh, among others, still has a crippled echo builtin that mis-handles backslashes. * build-aux/options-parser (bs_echo): Adopt the autoconf echo normalization code to find a suitable replacement for buggy echo commands. Adjust all uses of echo to $bs_echo. * build-aux/extract-trace (func_extract_trace, func_main): Likewise. * bootstrap: To retain some execution speed on platforms with buggy builtin echo, replace most occurrences of `echo' with `$bs_echo' - except where its arguments will obviously never contain backslashes or be overly long.
