Hirokazu MORIKAWA 8c501bf9fe toolchain/binutils: v2.37 Close the file descriptor if there is no archive 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.

bfd: Close the file descriptor if there is no archive fd
Close the file descriptor if there is no archive plugin file descriptor
to avoid running out of file descriptors on thin archives with many
archive members.

descriptor there is no archive plugin file descriptor.
