Ingo Molnar 97f68e7287 zstd: Increase DYNAMIC_BMI2 GCC version cutoff from 4.8 to 11.0 to work around compiler segfault
[ Upstream commit 1400c87e6cac47eb243f260352c854474d9a9073 ]

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.
