Blosc is a high performance compressor optimized for binary data (i.e. floating
point numbers, integers and booleans). It has been designed to transmit data to
the processor cache faster than the traditional, non-compressed, direct memory
fetch approach via a memcpy() OS call. Blosc main goal is not just to reduce the
size of large datasets on-disk or in-memory, but also to accelerate memory-bound
computations.
C-Blosc2 is the new major version of C-Blosc, and tries hard to be backward
compatible with both the C-Blosc1 API and its in-memory format. However, the
reverse thing is generally not true; buffers generated with C-Blosc2 are not
format-compatible with C-Blosc1 (i.e. forward compatibility is not supported).

archivers/c-blosc2: fix build on powerpc64*
Build was broken with GCC with:
/wrkdirs/usr/ports/archivers/c-blosc2/work/c-blosc2-2.15.1/blosc/shuffle-altivec.c:
At top level:
/wrkdirs/usr/ports/archivers/c-blosc2/work/c-blosc2-2.15.1/blosc/shuffle-altivec.c:427:12:
error: conflicting types for 'is_shuffle_altivec'; have '__vector __bool int'
{aka 'const __vector(4) __bool int'}
427 | const bool is_shuffle_altivec = true;
| ^~~~~~~~~~~~~~~~~~
Go back to building with Clang and actually fix it - Clang has issues with
types like __vector uint8_t but accepts __vector unsigned char, which this
this commit changes.
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

archivers/c-blosc2: correct ppc64le condition
MATCHES should be used to allow for a regular expression.
STREQUAL was using the expression as a literal string.
