Package: libc6-amd64
Version: 2.27-4
Severity: normal
Dear Maintainer,
I was quite astonished to learn that upgrading libc6-amd64 took more
than a gigabyte of disk space. It seems libc6-x32 has the same
issue. The problem is in tehse files (from buildd logs(1)):
-rw-r--r-- root/root 4421064 2018-07-07 16:34 ./usr/libx32/gconv/BIG5HKSCS.so

These files normally take about 13 kB, but here they have 4 MB
each. Looking into the binaries
$ objdump -h CP1125.so
CP1125.so: file format elf32-x86-64

it seems that while the sizes are quite small together, the sections
from .init onwards are placed megabytes into the file.
Is that some problem with binutils?
