libreoffice build failed - hidden symbol referenced by DSO on netbsd-10 aarch64

[Paul Ripke <stix%stix.id.au@localhost>]

Error is:

2024-04-07-22:11:54: /usr/bin/ld: /home/tmp/pkgwrk/misc/libreoffice/work/libreoffice-24.2.1.2/workdir/LinkTarget/Executable/bestreversemap: hidden symbol `__aarch64_ldadd8_acq_rel' in /usr/pkg/gcc12/lib/gcc/aarch64--netbsd/12.3.0/libgcc.a(ldadd_8_4.o) is referenced by DSO
2024-04-07-22:11:54: /usr/bin/ld: final link failed: bad value
2024-04-07-22:11:54: collect2: error: ld returned 1 exit status

Searching the internets, it appears the easiest fix is to add
`-mno-outline-atomics` to compile opts. I have a build with this
running now which has made it past the previous failure.
