powerpc_ieee1275: Excluding the PKS for grub-emu on 32-bit PowerPC

Configuring the build with --with-platform=emu fails on 32-bit PowerPC with:

/usr/bin/ld: appendedsig.module: in function `grub_mod_init':
/home/glaubitz/grub/grub-core/commands/appendedsig/appendedsig.c:1615:(.text+0x2ab4): undefined reference to `grub_pks_get_keystore'
/usr/bin/ld: appendedsig.module: in function `create_dbs_from_pks':
/home/glaubitz/grub/grub-core/commands/appendedsig/appendedsig.c:1400:(.text+0x2c3c): undefined reference to `grub_pks_free_data'
collect2: error: ld returned 1 exit status

Fixing this by excluding the Platform Keystore (PKS) for grub-emu on 32-bit PowerPC.
