don't use Bash-specific ${parameter/pattern/string} expansion
sysdeps/unix/make-syscalls.sh and sysdeps/unix/Makefile use GNU Bash's ${parameter/pattern/string} parameter expansion. Non-Bash shells (e.g. dash or BusyBox ash when built with CONFIG_ASH_BASH_COMPAT disabled) don't support this expansion syntax. So glibc will fail to build when $(SHELL) expands to a path that isn't provided by Bash. An example build failure: for dir in [...]; do \ test -f $dir/syscalls.list && \ { sysdirs='[...]' \ asm_CPP='gcc -c -I[...] -D_LIBC_REENTRANT -include include/libc-symbols.h -DASSEMBLER -g -Wa,--noexecstack -E -x assembler-with-cpp' \ /bin/sh sysdeps/unix/make-syscalls.sh $dir || exit 1; }; \ test $dir = sysdeps/unix && break; \ done > [build-dir]/sysd-syscallsT sysdeps/unix/make-syscalls.sh: line 273: syntax error: bad substitution This patch simply replaces the three instances of the Bash-only syntax in these files with an echo and sed command substitution.
