h8300 on testsuite and -wrap

[Joel Sherrill]

Hi,

I am trying to run the gcc test suite on h8300-rtems
and getting lots of failures which look like this:

The arguments passed to ld look correct but looking
into this with a simple h8300-elf-gcc build, I noticed
that since gcc puts a leading _ on the symbols, you
have to pass "-Wl,-wrap,_malloc" NOT -Wl,-wrap,malloc".

Where is the leading underscore not getting dealt with
so the wrap functions get invoked.

FWIW I didn't see any h8300-elf results since last year
and wonder if this is a known issue.
