Bug ID: 27297
Summary: libctf.a malformed, build fails on
x86_64-apple-darwin18.7.0
Product: binutils
Version: 2.36
Status: NEW
Severity: normal
Priority: P2
Component: libctf

2.36 build log
I first encountered this problem when trying to build a pdp11-aout cross on
x86_64-apple-darwin18.7.0, but the problem is there for the native build as
well. I have not tested to see if other hosts are affected (this is all I
have). This build is using the macOS system tools (clang, etc.).
This problem does NOT occur with 2.35.2. It DOES occur with 2.36 and HEAD.
The problem arises here:

libctf_la-ctf-util.o libctf_la-ctf-open-bfd.o
This causes libctf.a to contain libintl.a as its first component file:
auge48> ar -t libctf/.libs/libctf.a

That causes the link of objdump to fail, ending the build:
