Did try the (relative new) support/scripts/test-pkg script with your patch/packet, two
failures until now:

- br-arcle-hs38 [ 4/47]: FAILED

Looks more like a toolchain support problem...I think nothing pcre2 specific...

- br-arm-cortex-m4-full [ 8/47]: FAILED

  src/pcre2grep.c: In function ?pcre2grep_callout?:

Missing 'depends on BR2_USE_MMU # fork' or maybe missing '--disable-pcre2grep-callout'
configure parameter in case of !BR2_USE_MMU?
