[PATCH v2 05/37] GDB: testsuite: powerpc: Don't return value from top-level (sed)

[Thiago Jung Bauermann <thiago.bauermann@linaro.org>]

This patch is purely the result of running:

$ sed -i 's/^    return -1/    return/' \
      aix*.exp* altivec*.exp* e500*.exp* powerpc*.exp* ppc*.exp* vsx*.exp*

and

$ sed -i 's/^    return 0/    return/' \
      aix*.exp* altivec*.exp* e500*.exp* powerpc*.exp* ppc*.exp* vsx*.exp*

inside gdb/testsuite/gdb.arch.

I didn't include changes made to return statements inside procedures.
