error while building leon3 with gcov flags

[Vijay Kumar Banerjee]

Hello,

I have added the following changes in the bsps/sparc/leon3/config/leon3.cfg

----------
CFLAGS_OPTIMIZE_V = -Os -g
CFLAGS_OPTIMIZE_V += -ftest-coverage
-------

While trying to build with these flags, I got a bunch of
the following errors:

==========
{standard input}: Assembler messages:
{standard input}:6510: Error: can't resolve `.data._SPARC_Counter'
{.data._SPARC_Counter section} - `.LLtext0' {.text section}
{standard input}:6511: Error: can't resolve `.data._SPARC_Counter'
{.data._SPARC_Counter section} - `.LLtext0' {.text section}

===================

after the `make install` I do get a lot of .gcno files, and no
executables.
