### Describe the bug, including details regarding any error messages, version, and platform. I am supporting a bundled build of libarrow in perspective's conda-forge feedstock. On the conda-forge arm64 cross-compiling builders, `/usr/bin/libtool` is broken due to some SDK issues ( [full logs](https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=1050424&view=logs&jobId=7df89df7-19f1-5ccc-b210-32c1d05c0f56&j=7df89df7-19f1-5ccc-b210-32c1d05c0f56&t=c5e4c004-2534-57b9-b739-c5013de31afa) ``` xcodebuild: error: SDK "/Applications/Xcode_15.2.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk" cannot be located. libtool: error: sh -c '/Applications/Xcode_15.2.app/Contents/Developer/usr/bin/xcodebuild -sdk /Applications/Xcode_15.2.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk -find libtool 2> /dev/null' failed with exit code 16384: (null) (errno=No such file or directory) xcode-select: Failed to locate 'libtool', requesting installation of command line developer tools. ``` There is some logic in BuildUtils.cmake to locate libtool for bundling using `find_program(libtool HINTS /usr/bin ...)`, which then fails: ``` CMake Error at /Users/runner/miniforge3/conda-bld/perspective_1728519868797/work/rust/target/aarch64-apple-darwin/release/build/perspective-server-a7d183a58ee31af1/out/build/arrow-src/cpp/cmake_modules/BuildUtils.cmake:116 (message): libtool found appears to be the incompatible GNU libtool: /usr/bin/libtool ``` In this build environment, the `LIBTOOL` environment variable is set by conda to the name of a suitable Apple libtool on the PATH. I would propose that if `LIBTOOL` is set in the environment, that BuildUtils.cmake ought to use it instead of calling `find_program`. To unblock us, I made this commit on top of 17.0.0 https://github.com/ProspectiveCo/arrow/commit/273a22873b3bdf2f88631441ba8fd80bc7a0dbf4. I'll use that as the basis for a PR to close this issue. I am new to arrow's build system and would be glad to hear better ideas of how to address this. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
