I tried building sqlite-3.32.3 and it works for a local build but when cross compiling I get the following error: sqlite-3.32.3: error: include location '/usr/include' is unsafe for cross-compilation [-Werror,-Wpoison-system-directories] sqlite-3.32.3: In file included from sqlite3.c:26208: sqlite-3.32.3: /usr/include/pthread.h:744:12: warning: declaration of built-in function '__sigsetjmp' requires the declaration of the 'jmp_buf' type, commonly provided in the header <setjmp.h>.

I am going to try to get steps to reproduce this on vanilla gentoo.
-I/usr/include is used equally used in this version and older versions of dev-db/sqlite. Building with normal GCC or normal Clang works for me. I have no cross-compilers here. Maybe error is only printed by cross Clang. Does cross GCC print error?
Source of -I/usr/include is TCL_INCLUDE_SPEC from dev-lang/tcl: /usr/lib32/tclConfig.sh:TCL_INCLUDE_SPEC='-I/usr/include' /usr/lib64/tclConfig.sh:TCL_INCLUDE_SPEC='-I/usr/include' (dev-db/sqlite and possibly other packages use TCL_INCLUDE_SPEC.) Since explicit -I/usr/include or -I${EPREFIX}/usr/include is not needed and harmful, dev-lang/tcl needs to be fixed to have: TCL_INCLUDE_SPEC=''
I tried to locally patch tcl and it isn't enough to replace TCL_INCLUDE_SPEC because doing so results in the error: error: include location '/usr/include/readline' is unsafe for cross-compilation
In sqlite-3.32.3.ebuild, after changing: - options+=(--with-readline-inc="-I${EPREFIX}/usr/include/readline") + options+=(--with-readline-inc="-I${ESYSROOT}/usr/include/readline") Is cross-compilation working?
With both changes yes, cross compilation is working. I have uploaded pull requests with those changes.

Thanks. This is at least fixed for the unstable version of dev-lang/tcl now.
