Binutils build directory path limitation?

[David Wuertele]

I need to write scripts to drive crosstool to build toolchains in any
location the user desires.  But I'm running into a path limitation,
which appears to be in binutils-2.17.50.0.12.  Unfortunately, I can't
change the binutils version (or my vendor will stop supporting me).
Does anyone know if this is a know issue in binutils, and whether
there is a patch?

Using crosstool to build a toolchain with a RESULT_TOP path 53
characters long works:

  $ env -i BINUTILS_DIR=binutils-2.17.50.0.12 GCC_CORE_DIR=gcc-3.4.6 \
    GCC_DIR=gcc-3.4.6 GDB_DIR=gdb-6.5 \
    GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.6 GLIBC_DIR=glibc-2.3.6 \
    GLIBC_EXTRA_CONFIG=--with-tls --enable-kernel=2.6.9 \
    LINUX_SANITIZED_HEADER_DIR=linux-libc-headers-2.6.12.0 \
    RESULT_TOP=/nightly/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx \
    SHELL=/bin/sh TARBALLS_DIR=/tarballs TARGET=mipsel-unknown-linux-gnu \
    TARGET_CFLAGS=-O2 -finline-limit=10000 \
    TOOLS_DIR=/nightly/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx sh all.sh \
    --notest --gdb > .log 2>&1

But using the exact same crosstool configuration to build a toolchain
with a RESULT_TOP path 54 characters long fails (sorry about the line
folding, but GMANE won't let me post wider than 80 columns):

  $ env -i BINUTILS_DIR=binutils-2.17.50.0.12 GCC_CORE_DIR=gcc-3.4.6 \
    GCC_DIR=gcc-3.4.6 GDB_DIR=gdb-6.5 \
    GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.6
    GLIBC_DIR=glibc-2.3.6 \
    GLIBC_EXTRA_CONFIG=--with-tls --enable-kernel=2.6.9 \
    LINUX_SANITIZED_HEADER_DIR=linux-libc-headers-2.6.12.0 \
    RESULT_TOP=/nightly/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx \
    SHELL=/bin/sh TARBALLS_DIR=/tarballs
    TARGET=mipsel-unknown-linux-gnu \
    TARGET_CFLAGS=-O2 -finline-limit=10000 \
    TOOLS_DIR=/nightly/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx sh
    all.sh \
    --notest --gdb > .log 2>&1
  $ tail -12 .log | fold -w 75
