toolchain/binutils: v2.37 Close the file descriptor if there is no ar…

…chive fd

This fixes the following build error:
/home/build/openwrt/staging_dir/toolchain-aarch64_cortex-a53_gcc-11.2.0_musl/lib/gcc/aarch64-openwrt-linux-musl/11.2.0/../../../../aarch64-openwrt-linux-musl/bin/ld: /home/sergey/openwrt2/build_dir/target-aarch64_cortex-a53_musl/node-v14.18.2/out/Release/obj.target/tools/v8_gypfiles/libv8_base_without_compiler.a: error adding symbols: malformed archive
collect2: error: ld returned 1 exit status

It's a bad error handling related to -EMFILE (too many open files). nodejs is probably just very close to open file limit.
