Bug#1143851: hppa-linux-gnu-gcc does not honor -ffreestanding, generating referencs to memset

Source: gcc-16
Version: 16.1.0-3

Building firmware with hppa and hppa64 gcc, with option
-ffreestanding.  Starting with gcc-16, the following code

    struct tpm_log_entry le = {
        .hdr.pcrindex = pcpes->pcrindex,
        .hdr.eventtype = pcpes->eventtype,
    };

causes the following error to me emitted at link time:

 hppa64-linux-gnu-ld.bfd: o64/ccode32flat.o: in function `hash_log_extend':
 ccode32flat.o.tmp.c:(.text+0x5400): undefined reference to `memset'
 hppa64-linux-gnu-ld.bfd: o64/ccode32flat.o(.text+0x5400): cannot reach memset
 ccode32flat.o.tmp.c:(.text+0x5400): relocation truncated to fit: R_PARISC_PCREL22F against undefined symbol `memset'

The struct in question is a bit large, so it really needs
some memory zeroing in this case.  But the compiler is given
-ffreestanding.

Just in case, the code in question links in libgcc.a, but
it doesn't help either.

Apparently this is only a problem for hppa (both 32 and 64 bits)
compilers, other compilers does the right thing here.

This code worked fine when built with gcc-15 and before.

Thanks,
