Unfortunately, some Linux systems (SuSE 7.3) are using an ld that has
the new evil -z combreloc option, but doesn't document it in ld --help
$ ld --help
...
-z defs Disallows undefined symbols
-z initfirst Mark DSO to be initialized first at runtime
-z interpose Mark object to interpose all DSOs but executable
-z loadfltr Mark object requiring immediate process
-z nodefaultlib Mark object not to use default search paths
-z nodelete Mark DSO non-deletable at runtime
-z nodlopen Mark DSO not available to dlopen
-z nodump Mark DSO not available to
dldump
-z now Mark object non-lazy runtime binding
-z origin Mark object requiring immediate $ORIGIN processing
at runtime
-z KEYWORD Ignored for Solaris compatibility

$ strings `which ld` | grep combreloc
combreloc
nocombreloc
$ ld --version
GNU ld 2.11.90.0.29
...
Now, the latest binutils snapshot _DOES_ include the help string we're
looking for in configure.in, so this problem will go away real soon.
Even though this bug affects me personally, I recommend not fixing it,
since no one should be using a pre-release binutils, and because it's
hard to come up with a portable fix.
E.g. you could try
PAGER=cat man ld | grep nocombreloc
but what if the man pages aren't installed?
You could try
strings `which ld` | grep nocombreloc
but what if there's a csh dot file config error or strings isn't
installed?
However, an addition to PROBLEMS, perhaps mentioning SuSE 7.3
specifically, might be a good idea.
