Two corrections.
relibc dependency restored. Dropping gcc13 from gcc-native's deps also
removed what transitively staged relibc's headers, leaving the sysroot
with no libc headers at all -- no fenv.h, so libstdc++'s <cfenv> failed
with 'fenv_t has not been declared in ::'.
That corrects my earlier diagnosis: relibc's fenv.h is NOT a stub. It
delegates to openlibm_fenv.h, which dispatches on __x86_64__ to
openlibm_fenv_amd64.h where fenv_t and fexcept_t are both defined, and
relibc stages all of those headers. The header was simply never reaching
this recipe's sysroot. The previous commit message asserting a relibc
fenv gap was wrong.
relibc gitlink bumped for the fnmatch commit, which adds the GNU
FNM_FILE_NAME and FNM_LEADING_DIR that GCC 16's libiberty needs.
