Building the ps3 toolchain on Apple M1 (arm64)

[bucanero]

I just got a new laptop (with Apple's M1 chip) and I had to rebuild the toolchain from scratch.

Good news: the PS3 toolchain and PSL1GHT SDK can be rebuilt on arm64 arch.
But... patches and fixes must be done here & there to compile. 😅

For the toolchain:

I had to fix gcc-7.2.0 with this patch 0023-apple-silicon.diff:

I also had to fix gdb-7.5.1 too, adding #include <sys/ioctl.h> in two files, as shown in #103

• Add lib paths on Apple M1 (arm64) #113
• Support apple M1 (arm64) PSL1GHT#129
