Bug#1057385: lighttpd FTCBFS: host CFLAGS leak into build compiler invocation
Source: lighttpd
Version: 1.4.73-1
User: debian-cross@lists.debian.org
Usertags: ftcbfs
X-Debbugs-Cc: debian-cross@lists.debian.org
Dear Maintainer,
some compiler flags are architecture specific and should not leak when
cross-building.
As an example, -fcf-protection is x86-specific, and the following fails:
aarch64-linux-gnu-gcc-13 -fcf-protection
Similarly, -mbranch-protection=standard is aarch64-specific, and the
following fails:
x86_64-linux-gnu-gcc-13 -mbranch-protection=standard
With the attached patch lighttpd cleanly cross-builds from source.
Emanuele
