[mips] Define macros related to -mabicalls in the preprocessor
Summary: Historically, NetBSD, FreeBSD and OpenBSD have defined the macro ABICALLS in the preprocessor when -mabicalls is in effect. Mainline GCC later defined __mips_abicalls when -mabicalls is in effect. This patch teaches the preprocessor to define these macros when appropriate. NetBSD does not require the ABICALLS macro. This resolves PR/31694. Thanks to Sean Bruno for highlighting this issue!
