[Bug Report] Git fails to compile with fortify-headers and LTO - error: inlining failed in call to 'always_inline' 'fwrite': function body can be overwritten at link time

Hi,

I'm currently testing Gentoo Hardened build using Musl and
fortify-headers which has has lead me to discover git (2.41.0) will
not compile when GCC has been built with fortify-headers -
https://github.com/jvoisin/fortify-headers and -flto enabled in
CFLAGS, it will however compile fine if you remove the -flto.

I've included what I think is the important bit below but will also
attach a full build log and system information  to hopefully give more
of a hint for possible causes.
