brooks added a parent revision: D50465: libsys: Use PICO_CFLAGS to disable syscall stubs.May 22 2025, 3:03 PM

I wish we had these documented somewhere, so we could include a note that ${SHARED_CFLAGS} (along with ${CFLAGS} and ${PIEO_CFLAGS}/${PICO_CFLAGS} etc.).

I see three SHARED_CFLAGS references: in lib/libc/sys/Makefile.inc (noted in the PR), share/mk/bsd.sanitizer.mk, and lib/libarchive/Makefile.inc. I'm not sure why libarchive's addition of ICONV-related flags are in SHARED_CFLAGS not CFLAGS.
