disable pcre_jit on x32 (segfaults)

this shouldn't be needed, as
- pcre2.spec the jit is disabled: https://github.com/pld-linux/pcre2/blob/auto/th/pcre2-10.33-1/pcre2.spec#L256
- and in ext/pcre/config0.m4 there's feature check: https://github.com/php/php-src/blob/php-7.4.0alpha1/ext/pcre/config0.m4#L54

however reality shows that doesn't work as the segfault building phar.phar backtrace includes pcre_jit symbols
