+Description: Fix "bad substitution" errors in shell script
+ make-syscalls.sh uses GNU Bash's "${parameter/pattern/string}" parameter
+ expansion.  Non-Bash shells (e.g. BusyBox ash built with CONFIG_ASH_BASH_COMPAT
+ disabled) don't support this syntax:
+ .

+        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; }; \
