Bug ID: 83971
Summary: gcc -static link command hardcoded when
--with-system-libunwind used
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org

example build log
Modern versions of libunwind include liblzma for decompressing compressed
symbol tables. So when gcc is built with --with-system-libunwind, static links
will fail because gcc is hardcoded to use "-lunwind" rather than the results of
"pkg-config --libs --static libunwind". As a result, liblzma.a is not included
when it should be.

for a full build log.
The problem seems to stem from gcc/gcc.c:init_spec()
