[Bug other/15176] New: [tree-ssa] Disable libmudflap without ld --wrap

Even after hacking libmudflap as described in PR libmudflap/15174 to
compile on Tru64 UNIX, all tests fail as follows:
In file included from <command line>:1:
../mf-runtime.h:92: warning: #pragma redefine_extname conflicts with declaration
/usr/bin/ld:
--wrap=main: Unknown flag
/usr/bin/ld: Usage: /usr/bin/ld [options] file [...]
collect2: ld returned 1 exit status
compiler exited with status 1
So if the linker used doesn't support --wrap (this will almost exclusively
be GNU ld) or some equivalent mechanism (I haven't found any on Solaris 2,
IRIX 6 or Tru64 UNIX, but AIX has and defines its own versions of
MFWRAP_SPEC and MFLIB_SPEC), libmudflap is currently useless even if it
compiles. I think the libmudflap configury should detect this and disable
libmudflap automatically if those prerequisites aren't met.
