stop allowing the "RCpc" extension
* with GCC 13, the compiler will automatically use instructions
in the LDAPR family; see
https://community.arm.com/arm-community-blogs/b/tools-software-ides-blog/posts/enabling-rcpc-in-gcc-and-llvm
* newest valgrind (3.22) does not recognize these instructions,
crashing the program with SIGILL
* removing the flag should effectively keep old (gcc 12) behavior,
so it seems to be the safest course for now.
