Add a GPROF=1 build option to enable gprof profiling for sandbox. This adds the -pg flag to both compiler and linker when GPROF=1 is set, following the same pattern as the existing FTRACE option. Usage: make GPROF=1 sandbox_defconfig all ./u-boot -T -c "ut dm" ... gprof u-boot gmon.out Co-developed-by: Claude <noreply@anthropic.com> Signed-off-by: Simon Glass <simon.glass@canonical.com>
