Ada: Fix build failure on Windows machines
This commit fixes an Ada build failure on Windows by removing the -E switch from the Makefile.
The Ada build process on Windows failed due to the -E switch not being recognized by older versions of GNU sed. This commit removes the switch, and the associated pipe, which also hid error messages, to fix the build.
In Details
The commit modifies the Makefile recipe for $(RTSDIR)/s-intnam.ads to use a basic invocation of 'sed'. The -E switch, used for suppressing the printing of file names, is removed to ensure compatibility with older GNU sed versions commonly found on Windows.
For Context
The 'sed' command is a stream editor often used in build processes to manipulate text. This commit addresses a compatibility issue where an option used with 'sed' is not supported on some Windows systems. By removing the problematic option, the build process is made more reliable across different environments.
