I modify src for RaspberryPi.
# uname -a

# ldd /usr/local/lib/libpcre.so.3
/usr/local/lib/libpcre.so.3:
libthr.so.3 => /lib/libthr.so.3 (0x20297000)
libc.so.7 => /lib/libc.so.7 (0x20100000)
I change src follows,
- 1. copy contrib/binutils/bfd/elf32-arm.c to gnu/usr.bin/binutils/libbfd/elf32-arm.c
- 2. change gnu/usr.bin/binutils/libbfd/elf32-arm.c by following diff,
diff -u contrib/binutils/bfd/elf32-arm.c
- gnu/usr.bin/binutils/libbfd/elf32-arm.c
