libstdc++: Use printf to print control characters
Bash and GNU echo do not interpret backslash escapes by default, so use
printf when printing \n or \t in strings.
libstdc++-v3/ChangeLog:
* testsuite/experimental/simd/generate_makefile.sh: Use printf
instead of echo when printing escape characters.
