toolchain/Config.in: sh4{eb, a, aeb} are affected by GCC bug 101737

pixman fails to build with BR2_OPTIMIZE_S on sh4{eb,a,aeb}:

In file included from pixman-fast-path.c:33:
pixman-fast-path.c: In function 'fast_composite_scaled_nearest_8888_565_normal_OVER':
pixman-inlines.h:586:1: internal compiler error: Segmentation fault
  586 | }
      | ^

Since all SuperH variants are affected, use BR2_sh instead of BR2_sh4.
