The pixman package exhibits gcc bug 101737 when built for the SH4
architecture with optimization enabled, which causes a build failure.
As done for other packages in Buildroot work around this gcc bug by
setting optimization to -O0 if BR2_TOOLCHAIN_HAS_GCC_BUG_101737=y.
Also let's add PIXMAN_CFLAGS and pass the Codesourcery work around CFLAGS
to it for consistency like we do for the rest of the packages.
Fixes:
