Comment:
Something like the following in the template should be fine:
```
export CFLAGS="${CFLAGS/-fstack-clash-protection/}"
```

yes, now i, using `export CFLAGS=$(sed 's/-fstack-clash-protection//g' <<<$CFLAGS) `
if it workaround is legal for package - then issue notabug
ps. option `-fstack-clash-protection` became in clang11

Comment:
There are a few packages that do something like this, if this is the only way to build it then sure.
But use bash substitutions instead of forking sed.

Closed issue by dinama on void-packages repository
https://github.com/void-linux/void-packages/issues/19839
Description:
Can't prepare package which using clang for build because shell `common/environment/configure/hardening.sh` set ` "-fstack-clash-protection -D_FORTIFY_SOURCE=2"` as default CFLAGS.
And compilation broken:
```
FAILED: CMakeFiles/cmTC_a2b73.dir/testCCompiler.c.o
/usr/lib/ccache/bin/clang -fstack-clash-protection -D_FORTIFY_SOURCE=2 \
-mtune=generic -O2 -pipe -o CMakeFiles/cmTC_a2b73.dir/testCCompiler.c.o \
-c testCCompiler.c
clang-9: error: unknown argument: '-fstack-clash-protection'
```
This workaround on <package>/template locally resolve this problem:
```
export CFLAGS=$(sed 's/-fstack-clash-protection//g' <<<$CFLAGS)
export CXXFLAGS=$(sed 's/-fstack-clash-protection//g' <<<$CXXFLAGS)
```

Hmm not sure if it should be closed. I think I can improve this one.
