relocatable-prog: Use wrapper-free installation also on Mac OS X. Reported by Paul Smith <psmith@gnu.org>. * build-aux/install-reloc: Accept a 'mode' argument as first argument. (func_relativize): New function, from gnulib-tool. Handle mode 'macosx' through invocations of 'otool' and 'install_name_tool'. * m4/relocatable.m4 (gl_RELOCATABLE_BODY): Determine use_macos_tools. If use_macos_tools is true, set INSTALL_PROGRAM_ENV to an 'install-reloc' invocation with mode 'macosx'.

The @code{c-strstr} module contains a substring search function operating
on single-byte character strings, that operate as if the locale encoding
was ASCII.
(The "C" locale on many systems has the locale encoding "ASCII".)

The function is:
@smallexample
extern char *c_strstr (const char *haystack, const char *needle);
@end smallexample

Note: The function @code{strstr} from @code{<string.h>} supports only
unibyte locales; for multibyte locales, you need the function
@code{mbsstr}.
