The reason for the error seems to be that the pkgconfig
are pointing to my system pkgconfig (which are of not writable)
$ ls -l /opt/sage/local/lib/pkgconfig/
total 52

With the option --without-system-openblas, the compilation fails at
openblas with
getarch.c:96: warning: "NO_AVX512" redefined
96 | #define NO_AVX512

there was a thread

just on this 10 days ago.
the system's openblas on Arch is broken, so you'd need to build with
---without-system-openblas
and also it might be related to

Dear all,
I am experiencing trouble compiling fflas_ffpack (in the sage
compilation process). It is the same error appearing multiple
times related to openblas_set_num_threads being not declared.
Note that I am running archlinux.
Best
Vincent
