Not everybody agrees that:
$ gcc helloworld.c
$ ./a.out
error: can't find libgcc_s.so.1
is a nice behaviour, or that LD_LIBRARY_PATH is ok to use, or is root, but
that's not the topic of this thread.
You can pass linker flags to the gcc build, you just don't use
LDFLAGS. With gcc 4.5 and later it's --with-boot-ldflags,
Maybe the paragraph about --with-gmp-lib could include a reference to
this new option, next to the mention of LD_LIBRARY_PATH?
I'm not
sure what the right trick is for gcc 4.4, maybe LDFLAGS_FOR_BUILD or
LDFLAGS_FOR_TARGET
or BOOT_LDFLAGS? ;-)
(note that it is not enough to export the variable in the environment,
BOOT_LDFLAGS=... has to be passed explicitly on the command line,
apparently)
