[OE-core] [dora][PATCH] libsoup: workaround oe-core mips-gcc ICE

[Mark Hatle]

From: Wenzong Fan <wenzong.fan at windriver.com>

(Note: this is being sent for Yocto Project compliance.  The bug is in the
 dora oe-core version of the compiler, but only if using -O0..  I consider
 it a temporary workaround.)

This error occurs for builds with the oe-core toolchain in debug builds:

    header-parsing.c:1263:1: internal compiler error: in dwarf2out_var_location, at dwarf2out.c:20810
     }
     ^
    ...
    Please submit a full bug report,
    with preprocessed source if appropriate.
    See <http://gcc.gnu.org/bugs.html> for instructions.
    {standard input}: Assembler messages:
    {standard input}: Warning: missing .end at end of assembly
    {standard input}: Error: open CFI at the end of file; missing .cfi_endproc directive
    make[3]: *** [header-parsing.o] Error 1

This happens only with optimization option '-O', so force to use '-O2' for mips
target to workaround this issue. Root cause will be addressed.
