configure: fix HAVE_GCC_ASM_CFI_DIRECTIVES check
* cipher/camellia-aesni-avx2-amd64.h (enc_blk1_32): Fix dual CFI_ENDPROC() usage. * configure.ac (gcry_cv_gcc_asm_cfi_directives): Add missing ';' after 'void asmfunc(void)'. * mpi/asm-common-i386.h: New. * mpi/i386/syntax.h: Remove CFI macros and instead include "asm-common-i386.h".
This was broken by commit 693ffa145378682229473b0e811a9cea7c4d307a
"build: Fix configure.ac for strict C99."
