tweaks for ARM32: recognize R_ARM_* relocations, and add -fno-unwind-tables to PIE_FLAGS.
linuxkm/linuxkm_wc_port.h:
* __PIE__: don't declare static pmd_to_page() unless USE_SPLIT_PMD_PTLOCKS.
* add wc_lkm_refcount_to_int() helper with -Wnested-externs suppressed.
wolfcrypt/src/fe_operations.c: in fe_frombytes() and fe_sq2(), use explicit XMEMSET()s to initialize working vars, rather than implicit, to avoid implicit (unshimmable) memset() calls.
wolfcrypt/src/ge_operations.c: fix gate on _wc_curve25519_dummy() to require CURVED25519_ASM.
