Describe the bug
Hi, there. I am using makefile to build zstd on linux and gcc, using commands as follows. And i found the compile flag -fno-tree-vectorize is missing since version v1.4.7. To be more actually, since commit e8eb293 #2368 。

clear && make clean && make -n

The compile flag only applies to the source file decompress/zstd_decompress_block.c，and comes from pr #1668。It seems to be a perf optimization on gcc platform.
Here is the output build on commit e8eb293, which missing the compile flag for perf optimization.

make -C ../lib libzstd.a

And build on commit 3e519be which just before the commit e8eb293, the compile flag is present.
And I also build on latest dev branch, still no -fno-tree-vectorize presents.

To Reproduce

git checkout 3e519be9656c586e2b80441929b1692adec21a9e
clear && make clean && make -n

Expected behavior
The compile flag should be present.
