zstd: Increase DYNAMIC_BMI2 GCC version cutoff from 4.8 to 11.0 to work around compiler segfault
Due to pending percpu improvements in -next, GCC9 and GCC10 are
crashing during the build with:
lib/zstd/compress/huf_compress.c:1033:1: internal compiler error: Segmentation fault
1033 | {
| ^
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-9/README.Bugs> for instructions.
The DYNAMIC_BMI2 feature is a known-challenging feature of
the ZSTD library, with an existing GCC quirk turning it off
for GCC versions below 4.8.
Increase the DYNAMIC_BMI2 version cutoff to GCC 11.0 - GCC 10.5
is the last version known to crash.
