;; muclibc / mglibc are defined in linux.opt, so we can't easily re-define |
;; how they are recorded. |
;; We could remove linux.opt from extra_options, but that could backfire if |
;; more options are added that we don't want to remove. Hence we use |
;; TARGET_HANDLE_OPTION. |
muclibc |
Target RejectNegative |
Use uClibc |
|
mglibc |
Target RejectNegative |
Use glibc (not supported) |
|
;; provide struct padding as in previous releases. |
;; Note that this will only affect STRUCTURE_SIZE_BOUNDARY, in particular |
;; make 2 byte structs 4-byte alignned and sized. |
