php & Oniguruma library

[donald]

• php with --enable-mbstring requires the Oniguruma regexp library, unless ----disable-mbregex is given, too 1
• mbregex is required by some softeware, e.g. LimeSurvey 6.3.9
• We don't have the Oniguruma library installed as a packge
• /usr/lib/libonig.a and /usr/lib/libonig.so were however installed by the package jq 2 which is a JSON parser, installed by jq - Command-line JSON processor #874
• jq: update from 1.5. to 1.7 #2988 switched jg to static only, so that now we only have /usr/lib/libonig.a
• As php extensions are shared object, we can no longer build php with --enable-mbstring

/usr/lib/gcc/x86_64-pc-linux-gnu/10.4.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/10.4.0/../../../../lib64/libonig.a(regparse.o): relocation R_X86_64_32S against symbol `onig_null_warn' can not be used when making a shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-pc-linux-gnu/10.4.0/../../../../x86_64-pc-linux-gnu/bin/ld: failed to set dynamic section sizes: bad value

We should have a bee package for Oniguruma (which includes the shared library) and the jq package should be prevented from installing libonig.
