PCRE JIT is not supported on most architectores: m68k, s390,
ia64 to name a few.
Example build failure is:
$ nix build -f. pkgsCross.s390.pcre
...
pcre_jit_compile.c:65:2: error: #error Unsupported architecture
The change shifts from --enable-jit[=yes] to --enable-jit=auto which
allows nixpkgs to enable jit automatically only on supported targets.

The PCRE library is a set of functions that implement regular
|
|
expression pattern matching using the same syntax and semantics as
|
|
Perl 5. PCRE has its own native API, as well as a set of wrapper
|
|
functions that correspond to the POSIX regular expression API. The
|
|
PCRE library is free, even for building proprietary software.
