gcc: add patch for sanitizer in gcc<11.1.0 (spack#25804)

acastanedam · web-flow · commit ca94240dd424 · 2021-09-08T15:57:42.000+02:00
This allows to fix the compilation of gcc versions less than 11.1.0,
due to the remove of cyclades of libsanitizer as it is described in
the patch:

The Linux kernel has removed the interface to cyclades from the latest
kernel headers due to them being orphaned for the past 13
years. libsanitizer uses this header when compiling against glibc, but
glibcs itself doesn't seem to have any references to cyclades. Further
more it seems that the driver is broken in the kernel and the firmware
doesn't seem to be available anymore. As such since this is breaking
the build of libsanitizer (and so the GCC bootstrap) it is proposed to
remove this.
