2023-03-10Revert ld ASCII supportAlan Modra1-24/+0
Revert "Prevent the ASCII linker script directive from generating huge amounts of padding if the size expression is not a constant." This reverts commit adbe951fc95943016325af08d677f18e8c177ac1. Revert "ld test asciz and ascii fails" This reverts the ascii.d part of commit 5f497256bee624f0fa470949aa41534093bc5b25. Revert "Add support for the ASCII directive inside linker scripts." This mostly reverts commit 9fe129a4105bb59398f73ce96938a94f19265b79 leaving the asciz.d and asciz.t changes in place.
